Hi all, I'm currently debugging a problem and digging into the Squid cache. I noticed that even with 2.6, "Accept-Encoding: gzip, deflate" used by IE and "Accept-Encoding: gzip,deflate" used by Firefox are considered 2 different values and so pages are cached twice when using a Vary: Accept-Encoding header. I may have misunderstood something but I had in mind this problem was at least partially fixed in 2.6 (mostly from this email of Henrik I read a long time ago: http://www.squid-cache.org/mail-archive/squid-users/200608/0249.html ). I use squid-2.6.STABLE6-4.el5 (the RHEL5 package maintained by RH). I checked the ChangeLog from 2.6-stable6 to stable17 and I didn't find anything relevant about this behaviour. Any hint on how to avoid this problem? Thanks. -- Guillaume
