I'm not really convinced. And I like how you call this a bug
('scuse me! you're not violating the protocol properly!)
With the original patch I sent a NOCACHE+IMS request is not forwarded,
and you don't really know if the page is stale.
With your patch, such a request would be forwarded. If you have a
parent cache, then the parent may or may not forward it on to the
origin (you may or may not see stale data). If you have no parents,
then the origin server will tell you if you have the current version
(you should never see stale data).
For some reason I thought the goal was to NOT forward the request
because the request forwarding caused delays. But maybe everyone has
something different in mind.
Maybe it would be better to just leave NOCACHE+IMS requests
alone (so they always go all the way to the origin) and
only munge NOCACHE requests without IMS headers.

Things to check:
1) The log directory exists
2) Squid owns the directory. i.e. the user that squid is running
as.
If I was running squid as say user "proxy" then got to squid's
home directory something like "/usr/local/squid" and type:
# chown -R proxy.proxygroup *
Assuming squid is running as "proxy" and is a member of
"proxygroup"
Sorry about being so specific.
Dave.

Yes, it may well be that we have slightly different ideas about what
the reload_into_ims flag should mean. The way I expected it to be:
o NOCACHE+IMS requests are handled *exactly* like regular IMS. In
other words we first go through the refresh_pattern checking and
only if it says the object is valid is the IMS taken into account.
o NOCACHE requests are handled as if the object is stale and needs
revalidation.
It seems we agree on the NOCACHE case. What I don't understand is why
you want NOCACHE+IMS to always regard the cached object as valid and
thus bypass the refresh_pattern staleness checking. At least to me it
doesn't feel right that NOCACHE+IMS is less inclined to forward the
request than just a plain IMS

At least on our site I see that the majority of the NOCACHE requests
coming in from the broken Netscape 4 browsers also have IMS set. Which
makes sense, the browsers have their own disk and/or memory cache and
generate IMS relative to it.

Hi all,
I am running Digital Unix 4.0a, Squid 1.1.11, Apache 1.2 on the same box.
All are working well together.
The problem:
After starting cachemgr.cgi and selecting any option from the drop down
list the following message appears eg.
info:proxy.is.here:3128
dated Fri Aug 8 10:56:42 1997
ERROR
Access Denied
Sorry, you are not currently allowed to request:
cache_object://proxy.is.here/info@
from this cache, Please check with the cache administrator if you believe
this is incorrect.
<<End of Problem
Please help, this is really starting to annoy me!!
Thanks
~Adam

Ensure that the userid executing the kill -USR1 has access to send signals
to the Squid process (particularly true under Solaris 2 I've noticed, less
necessary under Solaris 1).

wait a few more minutes, then you can see *.log.0

Well, that sounds like the dns-test doesn't work quite right or does take
much time.
Just change the option in your squid.conf: dns_testnames

Your boot scripts *have* started the named prior to squid starting up??
If you primary/secondary a lot of domains there may be a significant delay
before named is able to fulfil requests.
[this applies to other things that squid depends on - ie basic networking,
name service (even disk mounting....!). Squid needs to be started
pretty late in the sequence]

Hi,
After updating to Squid 1.1.14 on a SNI SVR4 box,
strange messages keep popping up in cache.log:
e.g.:
.... ipcacheChangeKey: from 'www.microsoft.com' to '23/www.microsoft.com'
.... ipcacheChangeKey: from 'www.microsoft.com' to '24/www.microsoft.com'
.... ipcacheChangeKey: from 'www.microsoft.com' to
'25/www.microsoft.com'
etc.
Is this an error? Everything seems to work fine though.
TIA,

I want to use a 7.3 GB cache partition for squid 1.1.14
If the cache_swap value is larger then 6000000 (eg. 6300000)
I get the following message:
WARNING: cache_swap (-2138734592 kbytes) is less than cache_mem (67108864
bytes).
This will cause serious problems with your cache!!!
Change your configuration file.
I don't want to use 2 partitions for the squid because
of backup/restore of all files.
Best regards,
Thomas Krause

I have to add this to the user's guide sometime:
-------------------------------
In the "Changing operating system settings to enhance squid" chapter
theres missing some information on how to enhance FreeBSD.
The point with FreeBSD is, that parameters on how many FD's and buffers
etc. are all configured by the MAXUSERS kernel configuration directive.
A good value should be something like number of simultaneous connections
multiplied by 1.5 or 2.0, depending of course what else the computer is doing.
I'm using 2.0 because I can afford some spare memory on this matter.
For example, putting MAXUSERS to 60 will get something about 1920 FD's
and 960 Max processes. That should be enough for all. :-).

As you see, this is a negative value, caused by the 32-Bit limitation (
about 4 Gig).

As i know no other solution, you`d have to use 2 partitions. If i am
wrong please informe me.

its most likely nothing to do with the DNS test at all.
i came across this one first with HP-UX 9.01. things that you put in the rc
files sometimes just exit (for no apparent reason).
rc scripts on HPUX that are started with #!/bin/sh can exit before the
programs running in there have dis-associated themselves from the shell.
either start squid using an 'at' job into the future (echo
/usr/local/squid/bin/RunCache | at now + 1 minute'), start RunCache via nohup,
or put a 'sleep 30' at the end of the rc script, after squid has been started.
INN suffers a similar fate.
cheers,
lincoln.

The cache_swap is in *MEGA*bytes. Set it to 6000 for 6GB.
You asked for 6.3 tera-bytes of cache...

As I know FreeBSD 2.1.7 has problems with more than 256 descriptors in
select(). And configure limits number of filedescriptors to 256.

I have personally seen a FreeBSD box with over 2000 concurrent TCP sessions
to the squid port. I didn't configure it though.

Thanks to all how have responded to me. I have received the cool hint
to use ssl_proxy together with the netscrape cache and so I have no
need to socksify squid anymore :-)
Thanks again

If anybody else has found and fixed this problem already, I'd appreciate a
pointer on a patch before I struggle through it myself. :-)
ftpget (both 1.1.10 and 1.1.14) does not process file entries in a directory
listing correctly when the filename contains a space (which can easily occur
on Windows NT servers...). The reported name (and the name in the generated
URL) is truncated at the space.
Cheers,
Scott

FWIW, I think Robert has a good point - I would prefer his behaviour.

Read the FAQ. Make sure you have the web server with the cachemgr.cgi
script in the ACL.
e.g.
acl manager proto cache_object
acl mywebserver src 1.2.3.4/255.255.255.255
http_access allow manager mywebserver
http_access deny manager
Make sure you have set up your web server security so that random people
can't just access your cachemgr.cgi.

I would also like an answer to this. The web page at squid.nlanr.net still
says the stable version is 1.1.11, and the most recent is 1.1.14, which
implies 1.1.14 is unstable. But people seem to be using it happily, so
what's the story?

Perhaps the PID in the file is stale or not there? I have a handy killall
program. I do 'killall -USR1 squid' Or rather.. LINUX has a handy
killall program.. dunno 'bout other *nixes.

I think that what the web page is indicating is that 1.1.11 is the latest
*proven* stable version. This does not necessarily imply that 1.1.14 is
unstable, just that it hasn't had time to be proven stable. I've been
using 1.1.14+retry here and it's been up for the last nine days without a
hitch, so I personally wouldn't call it "unstable."
(According to the registration database, there's five other sites besides
me running the retry patch, and I think the Austrian one has been up
longer, since I did a restart to back out a couple of changes I made
beyond the patch that Technodat is running.)

Everything's fine here, which would imply its something local to you. Does
other e-mail work 100%? You may also want to check your sendmail logs to
see if anything weird is happening there.
You should get two copies of this e-mail, one direct to you, and one via
squid-users.

I had this problem sometime back after moving the logs to /var/log
rather
than /usr/local/squid/logs. Everything worked fine except logfile
rotation.
I just moved the log files back to /usr/local/squid/logs because of a
space shortage en /var and presto the rotation problem was solved. I
never
saw an error from the kill process doing it manually or with cron. It
just didn't happen.

We have squid within the /usr/local/squid structure and we still can't seem
to get the rotate logfile function to work.

This is a lame patch, but it works for now. After it's applied, if ftpget
sees a DOS-format file listing and an entry contains more than 4 tokens, it
assumes the filename must contain whitespace and uses the exact (unparsed)
string as the name. My command of C is too feeble to come up with an
efficient and general way of determining where the filename really starts, so
I wouldn't call this patch a robust solution.
This patch is against ftpget.c 1.1.14.
Cheers anyway,
Scott

// As I know FreeBSD 2.1.7 has problems with more than 256 descriptors in

I've make some changes here when I was running 2.1.7, but I could not
check if that worked because I changed to 2.2 just a little after.
First, edit your kernel config file and add a line like this:
options "FD_SETSIZE=5120"
Or any other number of descriptors you feel you need.
Them, edit the squid sources and remove the limitation on 256 descriptors
if it detects FreeBSD 2.1.
Also, in rc.local, add some sysctl's to get more kern.maxfiles and
kern.maxfilesperproc.
If this really works, please tell us.

I guess this is a case of incorrect file/directory permissions. The
logs directory should be owned by the user running squid.

Hi,
We have been encountering regular occurences of squid going into DNS Fail
mode lately, this has not happened for some time, is there something that
someone knows about that causes this to happen.

Hi,
I was wondering if it would improve performance if I had a few
partitions on the same drive . Therefore Squid would spread the data
across the partitions right ? This is only a theory though . And
increase data output ?

any half-decent operating system (read: unix) will already endeavour
to spread files out across the disk (its only things like DOS' FAT
filesystem chose a scenario of always-allocate-at-beginning).
evidence of this is doing a fsck and see how (little) a unix filesystem
is fragmented.
no -- i don't think you'd gain any performance by partitioning.
you would, however, gain big-time on performance if you could stripe
a partition across multiple disks. write performance on a box here,
with a RAID-0 array across 3 fast-wide scsi busses of 2GB disks is
in excess of 10 megabytes/sec. and that is out of the box, without
any attempt to do any tuning.
cheers,
lincoln.

I've been running 1.1.10 with the multiple ports patch with great
success. I'd like to upgrade to 1.1.14. Does it have multiple port
support built in or do I have to wait for a patch? I'm not subscribed
to the list so please reply to the From_ address.

nope, 1.1.14 doesn't have the multiple-ports-patch built-in. it will,
however, be part of the up-coming 1.2.xx squid series.
the same patch as for 1.1.10 should apply (relatively) cleanly to
1.1.14, or at least with minimal modification (it should be fairly trivial).

lincoln.

Hello all!
There is a new version of the squid-docs out, and this time it has not one,
but two sections written by volunteers! (from 0 pages to 2 in one month,
and I have had another offer too!)
The following sections are new:
Log analysis and stats (Everyone say thank you to Mark Visser for this!)
Preloading pages
Optimisation/Optimization (And to Julian Anderson for this!)
Bottlenecks and performance issues
Malloc problems and memory usage
System software you can use to analyze squid
I have been trying to figure out a mirror policy... Here it is:
The origin page (http://cache.is.co.za/squid/) will now keep the date
of the last modification in the title. You can see if you have the latest
version by comparing against this page. The latest version is always going
to be at 'http://cache.is.co.za/squid-docs.tar.gz'.
I have had numerous request for a 'paper-friendly' version of the document.
It makes sense, so I am going to do it, but I am not sure when, since it
involves re-typing most of the document, basically.

my browser (Opera 2.12) can fetch it directly just fine.

My guess is that it's almost certainly the browser getting confused. I have
never seen this message and squid works perfectly with the above URL for
me. I am running 1.NOVM.10. 1.1.11 has been out too long for this bug to
have not shown up before now.

Hi,
I'm having problems with the "cache_effective_user" option in squid
version 1.NOVM.14 and 1.1.14. I tried to set this options to user
"nobody" and group "nobody", but it did not work. I tried to set to user
"squid" and group "adm", but again it did not work. Does somebody know
what I can do to do squid work?
Best regards,

Wrote the following to use Linux-Pam with Squid. It's based in part on
the mod_auth_pam writen by <ingo@blank.pages.de>.
Feel free to copy, modify, and/or distribute.
Next incremental improvement would be to make the service configurable via
squid.conf.

You woukldn't beleive it, if you add a http_access line as follows
"http_access allow localhost" and remove "!localhost" from the http_access
deny line. Then everything is hunky dory, Fantastic, it bloody works.
> acl localhost src 127.0.0.1/255.255.255.255
> acl all src 0.0.0.0/0.0.0.0
>
> http_access allow manager localhost
> http_access deny manager
Thanks for the help everyone.

(using squid 1.1.14)
I've found that when using squid to access FTP sites, it doesn't properly
convert the FTP 'readme' file to valid HTML. For example,
ftp://tsx-11.mit.edu/ has some 'to get <file>.gz' entries. ftpget does
not escape the < and > symbols as per HTML spec, thus my browser (netscape
3) tries to interpret them. I don't know if there are also other symbols
that aren't being escaped correctly.
Also, (squid-users), is it possible to disaply ftpget from converting ftp
listings to HTMLscript? I believe the old harvest cached could, but I
can't seem to find how to do this under squid.
Thanks!

Hi there...
Is there a retry or timeout value that can be set in Squid 1.NOVM.13
to stop it from doing the following:
Connection Reset By Peer
But if the user clicks on the URL link on the page, it loads fine...
Anyone help? :)

i think you may be right. MesSIE can fetch it through the proxy fine; and apparently there's a cookie goes with it (abuse.net abusing cookies? wonderful :). perhaps it's the combination of cookie and proxy that messes Opera up. now how am i going to show them *this* bug...
if i could figure out how to get Lynx to use a proxy i'd test it too :)
anyway, that was my one qualm keeping me from broadening its use by Tallships and now i think i'll let more of us in on it... thanks!

Lynx uses environment variables to configure Proxies. I'm not sure that
it also handles Cookies too. Fote Macrides maintains a number of up-to
date bug fixes and enhancements to Lynx (aside from being a Lynx
developer) and his Lynx-version-FM code is always quite good. Check out
Yahoo and do a search on Lynx. You'll find links to the current V2.7.1
version there.
Anyhow, under VMS, the environment variable (logical name) is HTTP_PROXY
or FTP_PROXY. Under Un*x I'd imagine it would be a case of setenv
HTTP_PROXY "http://your.proxy:port/" and similar for FTP. These *may*
need to be lower case - since I use a case insensitive O/S I can't tell
from here.
Good luck, and don't forget to check the Lynx FAQ

Alternative way is to setup those proxy settings in lynx.cfg config
file.

I'm running 2.2-STABLE (or 2.2.2) and use

I've been having the same problems. I recently upgraded our site-wide cache
from 1.1.10 to 1.1.14 with no problems. However, I'm setting up another cache
to test proxy_auth-entication and have installed 1.1.14 on there with a
fresh squid.conf file. I configured cache_effective_user and it would still
complain about that parameter not being set. I tried to get debugging info.
from squid, but to no avail. I put my own debugging messages in there
recompiled it, installed it, ran it and then it worked fine ?? I then
realised I'd forgotten to define HAVE_PROXY_AUTH in the src/Makefile so I
added that and recompiled and installed. Now it doesn't work and my
debugging messages are showing that cache_effective_user is now empty
after parseConfigFile has been performed ??? Something seems amiss here?

in fact, it looks like an interaction bug between browser and their server
(which happens to also be using Squid 1.1.5 as an accelerator)
I can certainly get it to come up with odd redirections like 'Location:
http://spam.abuse.net:2784/spam//spam/', especially if you miss off the
trailing '/' from the first URL.

i refound a page that had been doing odd things: <URL:http://www.furnation.com/artists.html> itself works fine, but trying to follow any artist's anchor causes a bad rewrite. the anchors require a redirect (no traling solidus); again there are cookies; *but* you can correct the URL manually and it will work (unlike the spam page). Again it affects Opera but not MesSIE or Lynx.

Hi Folks, I have installed a couple of days ago a rpm of squid (1.1.11 I
think) and installed without problems.
I have searched the rpm but could not find the RunCache script that I used
to run in a rc.local (when the system was based on a Slackware
distribution and squid 1.0.22).
Can I use such script with 1.1.x ? Where should I call it (rc3.d?) ?
Thanks.

I was wondering if other people think that having entries in the cache
information page for the high-water-mark values of things like
filedescriptors, ip cache entries, memory usage, and other such things,
would be useful?
I'm thinking that that would help a cache manager determine where such
values should be set, without having to wait for the cache to crash when
it overshoots the limits.

Hi all,
I got the attached message (see below) in my mailbox.
"dalet.belnet.be" is our network wide parent cache. Although I
don't think the request can be enforced, I'd like your opinions about
this and if possible pointers to 'official' documents commenting on this
issue.
Thanks,

Therefore, while I have no problem with your users visiting one or more of

I INSIST THAT YOU STOP COPYING FILES FROM MY SERVER IMMEDIATELY. I ALSO

FAILURE TO DO SO WILL RESULT IN LEGAL ACTION.
Thank you.

Easily fixed. Just deny access to pictographics.com to your users. A more
rational approach (in face of a frothing webmaster) is to use cache_stoplist
on his domain. Then your users will only be proxying his pages, not caching
them.
Alternatively, since you're in Belgium and he's in the US is to ignore him.

This is quite unbelieveable! Whenever anybody uses a modern browser then
objectsfrom a WWW site will be held in a local cache anyway, whats he
gunner do?
Sue the world?
Also, it is not you who are copying files from his server, it is your
users - he could just
as well say that he does not want any of his files to be stored in the
memory of your
router :)
Aparrently, at a meeting in Amsterdam some Legal people said that since
the files in
question would be freely avaliable on the net and since the cache server
is a public
service designed to make that public information more avaliable then the
question
of copyright violations is absurd. (Maybe not the exact words, taken
from a third party!)
I think that the chap first needs to be politely told what a cache
server is and what it does
as i suspect they are not too sure of this, the fact that it actually
makes their site faster
and more pleasurable for the end users to use is probobly oblivious to
them.
In any event, these sort of things have all too often been blown out of
all proportion by
people trying to protect themselves (As I suspect the above sompany is
doing) whilst
not quite understanding that what they object to is actually helping
them.
Funny old world!

Well, just looking at his legal crap it could appear that anyone who
wanted to view his homepages (it's just a lame web 'mall' - about 20 clients)
with the view to buy something from him/them isn't able to unless they
apply to use it for commercial purposes.
Reading it his way, he believes that the cached objects is 'one copy of the
material' and your proxy server isn't 'personal, non-commercial home
or educational use only'.
Since the site isn't a landmark site on the internet, just put in a redirect
to www.playboy.com or www.altavista.digital.com. Your users probably won't
notice, and may even be grateful in the end.
His beef, which he should come out right and say, is that his counters and
page access stats are pitiful and the 10 or so cached hits you got are
deeply offensive to him.

Block access to the site in question, wait for anything from his site to
flush out of your cache, and let the person in question know that you
have complied with his request. I can't see how this would make him
happy, but, well, it takes all kinds, I guess. :-/
I had a look at the site in question and noticed that there were some
Beatles samples on the site - I doubt that there would be too many sites
in the world allowed to distribute Beatles stuff (or use the Beatles
logo, for that matter). Anyone bored enough to contact The Beatles
management?
Ho hum.

Sure, but it defeats the whole purpose of having a cache in the first
place.

:-) my thinking too.
But the question really is, *is* there a copyright violation going
on here? After all, he could also complain that there are illegal copies
of is stuff sitting in the buffers of my routers, etc. In my opinion I'm
just providing an infrastructure that allow my users to efficiently
access documents publicly accessible on the Internet.

Bearing in mind that I'm no lawyer, I'd guess the relevant sections are:

By storing the information in a proxy's cache, it could be argued that the
proxy administrator is permitting, aiding or actually executing the
further distribution or republication of said cached material, outside the
terms granted by the copyright owner. (Washes out mouth.)
Of course, there exist "ways and means" of making your material
non-cacheable - perhaps this site should consider using them.
Cheers..

Why not mail the folks who are running the legality-laden web site and see
what their policy is on caches?

In my opiniom a caching-server (in this case a Web caching-server but it
also applies to other caching such as ordinary disk-caching servers) can
be considered as a (very) long network cable..

The problem has been solved. When running squid with high debug levels I
saw that all objects were considered too big to be cached. I saw that
maxobjectsize in squid.conf was way to high (81920000), the scanf() call
interpreting the number returned nonsense, probably 0.
It would be nice if the configuration code could perform some sanity checks
and issue a warning if something looks fishy...

There were already several comments on this, so I'll try to only point

Is anyone running anything to grab *every* file from his server? (Such
as one of the prefetch methods that have been talked about before on
this list)?) Perhaps a user, and you are just stuck in between holding
the files?
Also, I would write back that the request is unreasonable given that
the internet has standard ways to set a file to not to be cacheable or
to expire (which squid supports unless you patched it...) and that
*his* failure to follow the standards make *him* liable for them being
cached. Of course this does open up the issue for those sites that are
intentionally setting the headers and have some sort of legal speak and
those using a patched version of squid to cache the pages anyways...

Actually he is in Canada. Don't let him hear you call him American,
Canadians can get sensative about that kind of thing :)

I think the site should do something, if he don't like to cache, he can
expire the page, like M$ it do.
He also can give a message on his site that proxy is to turn off.
Finally he should read some books, that he can get the meaning of the
Internet, bandwith usage, .... Maybe he will need somebody who can read
the book for him.
He should get back to his job he was doing still last month ;-)
We have redirected his site to www.disney.com. and added him to the
bounce list (sendmail).
I don't deal with such newbies.

Indeed. I have heard that Netscape asked (in brutal legalese threats) one
of Australia's largest ISPs to stop caching their sites. The ISP said "no".
And that was it. Seriously, do you think it would be worth it to anyone to
pay lawyers a fortune to sue someone in a different country on a very
dubious basis just to get a few extra hits?
>But the question really is, *is* there a copyright violation going

The answer is probably not, but it hasn't been tested. You would expect
that proxy servers would be covered under any "fair use" provision of
copyright, but to date, I don't believe any legislation has been proposed
or any cases tried. And even if it had, you've still got the age-old
issue of international boundaries. So it's still up in the air (or on
the wires, if you like :-).
Cheers,
Marty.

hello everyone!
i wanted to prevent users from downloading files like .wav .viv .mov .mpeg
.mpg, etc. because the workstations they're using doesn't have multi-media
capabilities and it's just a waste of bandwidth if some curious kids
download these types of files.
how do i do it from the ACL entries?
thanks!

Could someone take the trouble of documenting all the options that can be
defined in src/Makefile.in in the FAQ (and/or Oskar's user guide). I would
do it myself, but the point is that I don't know what they all do!!!
Volunteers? I wouldn't have thought it would take long - just a short
paragraph per option.

Hi,
not in Germany it doesn't, and by inference probably neither does it in
the rest of the European Union, including Belgium.
In Germany there's a new law currently going through the legislative
process that's relevant here. A couple of months ago I read a draft
version; as far as I know, that draft is still pretty much what the end
version is going to look like.
As far as I remember, I was relieved to note that according to that draft
law, caching (described as automatic, user-demand driven(!)
store-and-forward mechanisms) is explicitly recognized *not* to violate
any copyright at all! Note the "user-demand driven", though:
pre-fetching probably _would_ constitute a violation! The central idea
is that caching is just part of the transmission process, as some people
on this list have been pointing out, "a very long line", and so is its
legal status. But in order for that to be its legal status, it has to fit
the discription: purely automatic (no human in the loop except to set up
and manage the general setup), purely "reactive" (i.e. no pre-fetch).
Another even more important aspect of that draftlaw from our point of view
is that we (running the cache) are explicitly not liable for any contents
of that cache (unless of course we ourselves caused it to be in there as
users): as an example, just owning child pornography is a federal offense
punishable by many years in prison around here (good thing, too) -- but
fortunately we're not tainted by a user who downloads such stuff via our
proxy server (which stores it, after all), much to our relief. Such a
user, of course, does face a prison sentence if he keeps the stuff around.
Despite this being in another country entirely, Belgium is part of the
same European Union -- so if push came to shove, it shouldn't be too
difficult to make a case that this German law does set a precedent in its
neighbor country.
(Oh, and this is NOT legal advice, of course ;-)
Best, Andreas

I'm trying to have squid use multiple cache directories. The config
file claims you can use multiple cache_dir lines to spread out your
cache, but there is only one cache_swap setting to set the maximum
size. I would like to be able to set a size for each directory. If
the cache_swap is set to be greater than the space on the first
disk, will it automatically use the second, crash, or use equal amonts
on both?
Is it possible to control how big each cache_swap is, and if so, how?
Thanks,
frank

Isn't the default squid.conf commented well enough? And if the comments
are not sufficient.. check out the Release-1.1 notes in the source tree.

You administrative fascist! :-)
I am also a bit of a fascist here. We don't like ppl accessing web chat
becasuse they spend hours on it and there are ppl that need the lab
computers to do homework. Create acl's like this:
acl nochat src 207.57.233.128/27 207.57.239.0/24
...
acl chatdot url_regex http://chat.*
http_access deny chatdot nochat
(we have MANY more per site restrictions... hundreds even.)
i.e. you might have "acl mpeg url_regex *.mpg"
Hope that helps
Matt

Sounds like he was worried about people not getting the most up-to-date

This seems to be a pretty common concern from people who don't understand
a lot about web caching. Perhaps a explanatory page could be added to the
Squid web page, going over the miscellany of Expires: headers and
If-Modified-Since requests?

Isn't this in the FAQ??
Ecah cache_dir has to be of equal size. It you have two disks where one
is twice the size of the other you have to divide the first disk in two
cache_dir's (not partitions..)

Don't overdo it, though - we don't won't half the Web to suddenly be

Seems like the discussion did some good after all. Below is a new

I wonder whether the 'discussion with my legal people' refers to an
email conversation with Kip DeGraaf... :-)

Dear Jan,
I have looked into proxy server issues further and have discussed it over
with my legal people. They suggest that proxy servers pose no problem or
conflict with the terms and conditions as stated by Pictographics, Ltd.
Apparently I was a little hasty sending out my email of Sunday morning. As
clarification, please disregard my previous two emails and cache away!!
Thanks in advance.

How about this. Every person that is using squid or any other cache
(or even if you are using netscape with the built-in disk cache turned on)
send him a (not 5000...) copy of this message with the appropriate stuff
changed. I just did. Let him know that he should get a clue before
he goes crazy.

We (cache.is.co.za) also cache your web pages. If you do not wish them to
be saved here feel free to sue us. If there are too many of us, perhaps you
would think about trying to use the STANDARDS, which our software obeys,
so that we don't cache pages. It's a little akin to putting a digital
'Copyright' signature on a page... but something that machines can read.

Okay, wait a second. Pictographics has gotten the message and understands
what a caching proxy really does. Let's not alienate the gentleman in the
process. Look at the last messages from myself and Jan Torreele, we've
both had reasonable and pleasant exchanges with the site.
(Of course, if he hadn't been reasonable, this sounds like an interesting
idea)

Hi Squiders,
what does "Page faults with physical i/o: 4897" in my Cachemgr "Cache

Hi,
The cache log is showing quite a few of these errors - between 40-80
each day.
97/08/13 16:35:38| comm_accept: FD 50: accept failure: (71) Protocol
error
97/08/13 16:35:38| asciiHandleConn: FD 50: accept failure: (71) Protocol
error

error
97/08/13 16:35:38| asciiHandleConn: FD 50: accept failure: (71) Protocol
error
FD 50 is the HTTP socket.
Anyone got any idea as to what's causing these ?
UltraSPARC, Solaris 2.5.1, Squid 1.1.15 (occurred with 1.1.11 too).
Browsers are mainly Netscape (version 2->4) and MSIE.
Thanks,
Niall

You get a "page fault", when your OS tries to access something in memory
which is actually swapped to disk. The term "page fault", while correct at
the kernel and CPU level, is a bit deceptive to a user, as there's no
actual error - this is a normal feature of operation.
Also, this doesn't necessarily mean your squid is swapping by that much.
Most operating systems also implement paging for executables, so that only
sections of the executable which are actually used are read from disk into
memory. Also, whenever squid needs more memory, the fact that the memory
was allocated will show up in the page faults.
However, if the number of faults is unusually high, and getting bigger,
this could mean that squid is swapping. Another way to verify this is using
a program called "vmstat" which is found on most UNIX platforms. If you run
this as "vmstat 5", this will update a display every 5 seconds. This can
tell you if the system as a whole is swapping a lot (see your local man
page for vmstat for more information).
It is very bad for squid to swap, as every single request will be blocked
until the requested data is swapped in. It is better to tweak the cache_mem
and/or memory_pools setting in squid.conf, or switch to the NOVM versions
of squid, than allow this to happen.
[To Duane: Could this be added to the FAQ in the cache manager section,
assuming no-one has any objections?]

Maybe /usr/local/squid/cache directory's write permission is not allowed
or owner might be wrong.
Check this point first.

This is a really interesting idea, similar to what others have proposed
or asked for. There is only one thing preventing this from being
really easy to implement: Squid and ICP don't have any concept of
third-party caches. At one point there was another cache package
(mirror-image?) which was going to implment third-party "redirections"
with ICP. There are a couple of ways the ICP relay could be
implemented with some modifications/additions to ICP. If anyone is
seriously interested in building one of these, please let me know and
we can work it all out.

The port 0 is definately wrong. Which version are you running?
Can you send more of the cache.log messages before this error?

I believe that you'd need to modify the source for this. Squid
tries to be persistent and if the DNS lookup fails locally it
forwards the request on to a parent which might have better luck
getting the address resolved.

Hi
I'm a newbie to squid and need some advice. The users are having a
problem with accessing one site. It is a online-workgroup area, but
doesn't use things like cgi-bin or ? in the urls and the proxy is caching all
the pages. This is a major problem and we need to sort it out. I'm not too
sure of the extensions to the pages.
Does anyone have any suggestions on this problem.
Bruce Smith

Hi,
We have configured our Squid Proxy server as a sibling of another Proxy
server and our Parent is currently using another Proxy server as its parent.
Do we need to configure our Parent's Parent proxies as well as our Parent
proxy or will a request from us to our Parent handle the requests to our
Parent's Parent??
P.S. Did you understand the question??

Bruce,
The tags "cache_stoplist" and "hierarchy_stoplist" will help you
out. Just add in the domain or page name, or something else significant
and that will fix it up for you.
Example: If I had a page that was somewhere in the world that I
know is being continually update, let's say:
http://www.somewhere.com/page.html
I would put in hierarchy_stoplist:
hierarchy_stoplist cgi ? www.somewhere.com/page.html
and in "cache_stoplist"
cache_stoplist cgi ? www.somewhere.com/page.html
That information is significant enough to tell squid that I do not
want the page to be cached locally and do not want to fetch the page from
a sibling or parent. It will then always get it from the source.
Seeya,
Dave.

Hi
One of our Intranet sites is using HTTPS, which I have deduced is HTTP over
SSL and hence non cacheable. Am I correct so far ?
The site is using Basic authentication to gain entry to either a HTTP or a
HTTPS directory tree (same information in both, but Basic authentication
credentials causes IIS Active-Server pages change the menus in both too).
I think they're really only worried about preventing orders taking place
on their electronic shopping-basket parts inventory system. The rest is
pretty plain old surfing as far as I have been able to determine (and
doesn't really need HTTPS at all).
Is there any way to make part of a site non SSL e.g. the GIF/JPEG images
which are just bandwidth hogs, thus improve the caching, but to still be
able to provide security on HTTP POST and GET requests (such as to the
order system) ?
OR, do they have to use two different realms so that the browser can work
out which parts are SSL HTTPS requests, and which are plain old HTTP. Can
such a mixed environment even exist ?
At present for HTTPS Squid can only act as a PROXY, forwarding requests,
and not a CACHE, storing the data, for SSL CONNECTs - am I right ?

: This seems to be a pretty common concern from people who don't understand
: a lot about web caching. Perhaps a explanatory page could be added to the
: Squid web page, going over the miscellany of Expires: headers and
: If-Modified-Since requests?
:
: -Mike Pelletier.
And how about some piece of information about -in my opinion-
badly configured webservers:
Apache has by default:
# CacheNegotiatedDocs: By default, Apache sends Pragma: no-cache with each
# document that was negotiated on the basis of content. This asks proxy
# servers not to cache the document. Uncommenting the following line disables
# this behavior, and proxies will be allowed to cache the documents.
# CacheNegotiatedDocs
Every website that uses an out-of-the-box configuration, like Slackware
has this turned off by default..
Personally i feel that this option SHOULD be ON by default !

Thanks Ian for the prompt reply.
Checking my store.log I see that yes, any access-controlled object only
appears as a "RELEASE" entry, and icp.c also indicates that it is indeed
non-cacheable.
Making GIFs and JPEGs anonymously-readable sounds like it requires a
code hack in icp.c which tests not only for authorisation, but for the
file extension too. Basically say, "what the heck" to GIF or JPG file
extensions.
Quite do-able if I had the time. Anyone already created such a hack and
care to share the code ?
I wish that we weren't so authentication-crazed around my company some
times.
Just putting the images in a different realm (moving the protected
documents down a different directory tree or images moved to another
server) would do the trick, wouldn't it ?
Anyone care to shed more light on this thorny subject ?

It's not possible at all. But ftp-gw gateway from TIS Internet
Firewall Toolkit works fine with WS_FTP. See

Hi,
yesterday I ran into some trouble with a customers apache and my squid.
I wanted to enable apache's agentlog by useing the oldfashioned way
(mod_agent_log) and not going via custom_log (I will try that today). But
when I started the apache and tried to access the pages via my squid it
didn't work. Netscape said "connected..." but it couldn't recieve any data.
Without using squid everything worked fine (netscape and telnet). The
squid-logs didn't contain anything unnormal....
Has anyone any ideas?
thanks and ciao,
markus

[ I'll call your parent A and your parent's parent B. ]
You don't need to, but there are advantages if you did if A goes down.
What you could do is put both in as parents in squid.conf, but add a
"weight=<number>" to A.
That way it prefers A, but will use B if necessary.

If it was negotiated, though, doesn't that mean that the content is
subject to change based on individual user input? If it's cached, won't
that mean that there's a possibility of a user getting someone else's
negotiated document?
I guess I'm not really clear what they mean by this...

I asked this because I am wondering a little:
The machine and Squid are now running 1 day, 6 hours, and Cachemgr says:
Squid Object Cache: Version 1.NOVM.15

^^^^^
Ok, but procinfo says:

If what procinfo says is true there were only 5 swap in and 21 swap out - so
why has squid 51826 page faults with physical i/o ?!

That's certainly my (mis-)understanding of what it's about. Documents where
what was returned in response to a request is determined by criteria
(language, content-type, content "quality" (e.g. image compression loss),
etc.) from among multiple documents (or generated dynamically in the form
required). The only time it would be sensible to allow caching of such
documents is if you (as origin server admin) know that although the documents
could differ, the variants are sufficiently similar that it wouldn't really
make much difference which version someone received. (In which case, it's
not obvious that there would be any point in supporting multiple variants.)
Even if a cache server kept track of all the response headers that could be
used in content negotiation, I can't see that it would be reasonable in
general to return a cached copy unless it could e.g. check (conditional GET)
what the origin server would have sent, and confirm that it has a current
cached copy of *that* variant. Simply applying variant selection criteria to
any variants that happened to be in the cache would not be sufficient, since
the cache could not know whether the origin server could offer a vastly
better match to the user's requirements than any of the variants that
happened by chance to be in the cache.
For example, consider a request specifying that the user would prefer the
document in Icelandic, but would accept English if necessary, and the only
cached copy was in Russian. Returning the Russian version or rejecting the
request as impossible to satisfy would both be unreasonable. If the cache
also had the English version, returning that would be more reasonable, but
still giving the user poor service when the origin server could have
provided precisely what had been requested. [The HTTP 1.1 spec has a lot of
comments on caching, and I haven't checked what it says about negotiated
documents, so it may mandate a different approach...]

Maybe I _slightly_ oversimplified, because OS's these days (not counting
MeSsy Windoze) only swap in and out _data_. They page fault when loading
executables and whenever malloc'ed regions are actually _used_ (rather than
just allocated) (generally). Executable code gets discarded rather than
swapped when memory is short, and reloaded directly from the executable.
That's why deleting an executable while its running is a hazardous activity.
There are other complications that arise with copy-on-write when fork() is
called, or if mmap() is used, but these don't affect squid.
Upgrading /bin/sh and a shared libc can be fun sometimes!
You must be hardly using your swap at all given your statistics. If you
type "free", or "top" you should get statistics saying that your swap usage
is near zero - at least according to what you've said above.

Hasn't this anything to do with the "NOVM" version?
My squid (1.1.14) has run for two weeks now, and has a pagefaultcount of
only 12 !

If each person on this list simply told him that they were caching
things, perhaps he would realise that caching is mailstream, and that
he should think before he threatens.

I wouldn't mind working on this (limited programming experience, I am
afraid). Here is our scenario:
We (currently) have 3 large caches, when we configure a client cache
to point to us as a parent we generally set them up with the
'default no-query' options, so that they hit us for an object. Squid chooses
one of the caches as it's default parent (we have one A record pointing to
multiple IP addresses). Since it does a TCP request to this cache (say
cache1, for example) cache1 will query cache2 and cache3 on it's behalf.
This means that we get effective use of our disk cache.
If they aren't setup to point to us as a parent, however (due to all sorts
of reasons that enforce this), we have to configure them as follows:
cache_host sibling cache1 ...
cache_host sibling cache2 ...
cache_host sibling cache3 ...
Now this means that they have 3 queries coming up their line and 3 going
down... and if there is one of these packets lost coz they are flooding
their line the cache slooows down.
When I spoke to you (a while ago) you said:
---------
HIT. Then you could use the 'redirect' opcode to make the querying
cache go to the right place.
---------
2. ICP Opcodes
The following table shows currently defined ICP opcodes:
Value Name
----- -----------------
0 ICP_OP_INVALID
1 ICP_OP_QUERY
2 ICP_OP_HIT
3 ICP_OP_MISS
4 ICP_OP_ERR
5-9 UNUSED
10 ICP_OP_SECHO
11 ICP_OP_DECHO
12-20 UNUSED
21 ICP_OP_MISS_NOFETCH
22 ICP_OP_DENIED
23 ICP_OP_HIT_OBJ
I can't see one... if there was one it would be fairly easy (relative to
the whole of squid ;') to write a 'concentrator', so they point to
cache-sibling.is.co.za, which does a query of each and every sibling
and sends a reply, with a 'redirect to cache1.is.co.za'.... there will
probably be security implications in handling this though.

Hi Squiders,
in http://cache.is.co.za/squid/opt/performance.html it is written that
turning up debugging would result in a 10-15% fast select loop.
I have some questions about this:
1) Where/how can I disable debugging ?
2) What exactely happens when debugging is tuerned of, has this any
influence on a normal running cache ? I mean what negative things
could happen when I turn debugging of - are errors/Problems still
logged in cache.log ? (what is it than I turn off and don't have any
more?
3) How are your experiences whith this ?
4) Are there any other usefull ways for tuning Squid or the machine
squid is running on, not mentioned on the above URL ?
(machines are all Pentiums 90-166, 64 MB, SCSII, running Linux 2.0.30
with fd_patch and Squid 1.NOVM.15)
And, a little offtoppic: I am searching tips for tuneing an other
Linux machine (2xP166 SMP, 128 MB) with with inn as news- and uucp
server, too. Perhaps anybody knows some good resources?
Many TIA,
Andreas

You'll certainly get different results from the NOVM as you won't get page
faults from malloc'ed memory. But in your case, I imagine that its just the
way your OS counts page faults. Yours might only change this stat if there
is a genuine swap out and in, rather than the other murky things to do with
demand-loading executables and malloc'ed memory that I've been talking
about. What OS is it?
Jonathan L.
P.S. For those interested, what happens is that malloc() allocates memory
in blocks, and when all the blocks are full up, calls sbrk() which calls
mmap().
The result is that in a sense you only reserve extra memory in the page
tables, but you don't _actually_ allocate it. Its only when the memory is
written to, that it is actually allocated a real chunk of (virtual) memory.
Some (most?) OS's make the program seg fault if you try to read from a page
of unallocated virtual memory even though it is in your page tables, as
this normally indicates you're reading from uninitialised memory.

Since your client is treating your neighbours as siblings, you
could probably easily mimic want you want by configuring a cache (that you manage)
to query these 3 siblings for your clients cache.
Your client would use this "hacked squid" cache as a parent, but you would hack
it so it returns ICP_OP_MISS_NOFETCH when it has not found the object in its
own cache and that of the 3 siblings it queries.
Note: I am assuming here that the hacked parent will query its siblings for the
object before returning a ICP_OP_MISS_NOFETCH.
A ICP_OP_MISS_NOFETCH reply effectively tells the originating squid
"Yes you have requested an object, but im busy reloading my log, so im not going to fetch
the object for you.. Get it yourself".

Well, this is rather interesting. I haven't been following this thread really
closely, but i happened to notice the domain in question here. As it turns out,
this individual is one of our isdn customers(small world). I guess he doesn't
realize that we too run a proxy server, and guess what, his pages are cached here
too:).
