[squid-users] purge from cache

hello all,

after having started with a clean cache on February, 14th
my cache-folder has meanwhile increased to a size of
68 GB, which makes 96 % of the available space on that
partition.

I am using squid as an accelerating proxy. All cached
objects should expire after 24 hours at the latest.

However, there are still objects as e.g.
~/cache/01/01/00100040 which has been saved on March, 8th
and where the header within the cache-object says:

Date: Mon, 08 Mar 2004 06:41:59 GMT
Server: Apache/1.3.29 (Unix)
Cache-Control: max-age=1800
Expires: Mon, 08 Mar 2004 07:11:59 GMT
...
...

Now I wonder: Why hasn't this object been purged by squid yet?

Squid just consumes more and more diskspace, until 100 % is full,
and then crashes. Shouldn't squid be able to purge these files
automatically after expiration time?

What I do now, is to start with a clean cache after 40-50 days.
The cachedir then immediately increases by 2-3 GB every day.

But that's not the way it is supposed to work, is it?

What am I doing wrong?

Any hints appreciated,

thank you
