[squid-users] crazy delay pools

Hi guys,
I have a very annoying problem and maybe someone here might be able to help
me.

Here's the thing: I have squid setup with delay pools in the following
config:

acl files urlpath_regex -i "/etc/squid/files"

delay_pools 3
delay_class 1 3
delay_class 2 3
delay_class 3 3

delay_parameters 1 -1/-1 -1/-1 8192/8192
delay_parameters 2 -1/-1 -1/-1 4096/4096
delay_parameters 3 -1/-1 -1/-1 16384/16384

delay_access 1 deny nolimit
delay_access 1 deny clients-32k
delay_access 1 deny clients-128k
delay_access 1 allow files
delay_access 1 deny all

delay_access 2 deny clients-64k
delay_access 2 deny clients-128k
delay_access 2 deny nolimit
delay_access 2 allow files
delay_access 2 deny all

delay_access 3 deny nolimit
delay_access 3 deny clients-64k
delay_access 3 deny clients-32k
delay_access 3 allow files
delay_access 3 deny all

contents of /etc/squid/files

\.exe$
\.com$
\.mp3$
\.mp2$
\.vqf$
\.tbz$
\.tar$
\.gz$
\.bz2$
\.rpm$
....and so on

Basically what I need to do is limit the download of specific file types (by
extension). This works for most of the users, but I get reports from various
people that by using DAP (download accelerator) with "extreme acceleration
speed" setting, the can override the limits that I impose. Why is this
happening? I tested the setup with FlashGet, GetRight and other download
managers, but only with DAP I have managed to get these unexpected results.

I'm using squid-2.5.STABLE9-2 on a RH 9

Anybody knows why and maybe what I can do to stop this?

Alex
