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:

Squid 3.1 doesn't have the storeurl_rewrite_program parameters, required to cache query parameters. There is no way to do that.
