[squid-users] Squid 3.0 as reverse proxy

Hi List,

I use a Squid Cache version 3.0.STABLE16 as reverse proxy on an 100Mb server (hosted by Iliad) to cache my web sites running on my home connection (1024Kb Max).

This configuration Works pretty fine, but I have troubles to cache some images (jpg|png) with a particular url:

For example, I have a photos gallery where the link to download the original picture (biggest size) has a "?" at the end:

http://gallery.wenske.fr/wallpapers/holland_dream_2560x1600.jpg.html?

In the access log I can see that this object is not cached:

23/Nov/2009:15:17:43 +0100.960 12372 84.207.23.135 TCP_MISS/200 1313021 GET http://gallery.wenske.fr/wallpapers/holland_dream_2560x1600.jpg.html? - DEFAULT_PARENT/sl01 image/jpeg

(store.log, may be helpful: 1258985863.960 RELEASE -1 FFFFFFFF B8B54D74210C1D0090AA8E1390D77D9C 200 1258985851 1258985851 375007920 image/jpeg -1/1312295 GET http://gallery.wenske.fr/wallpapers/holland_dream_2560x1600.jpg.html?)

I suppose that's due to this directive in the squid.conf:

hierarchy_stoplist cgi-bin ?

Is it possible to enable caching for this kind of url? Maybe with a regex?

Thanks for your help,

Sébastien WENSKE
