Squid: caching *.swf with variables
- by stfn
I'd recently upgraded my Ubuntu 11.10 x64 server to 12.04. In this process Squid was updated from 2.7 to 3.1. Squid 3.1 has many different options witch broke my setup. So I completely removed squid 2.7 and 3.1 and started from scratch. Everything is now working as before except for 1 thing: caching of .swf files with ?/variables. Squid 3 sees a ? as dynamic content and does not cache it.
For example, Squid 2.7 was caching the .swf file at http://ninjakiwi.com/Games/Tower-Defense/Play/Bloons-Tower-Defense-5.html and 3.1 is not.
<object id="mov" name="movn" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="800" height="620">
<param name="movie" value="http://www.ninjakiwifiles.com/Games/gameswfs/btd5.swf?v=160512-2">
<param name="allowscriptaccess" value="always">
<param name="bgcolor" value="#000000">
<param name="flashvars" value="file=http://www.ninjakiwifiles.com/Games/gameswfs/btd5-dat.swf?v=280512">
<p>Get Flash play Ninja Kiwi games.</p>
</object>
It is because of the "?v=160512-2" and "?v=280512" part. This line should be responsible for that:
refresh_pattern -i (/cgi-bin/|\?) 0 0% 0
But disabling it still doesn't cache the .swf files.
How do I configure Squid 3.1 to cache those files?
My current config is:
