Okay So still working thru some http 1.1 issues as we keep finding more "well that won't work".. Due to various "bugs" in IE 4-6 we have to return 1.1 or they get a script error (it's a .js file). "tested both on ie7 and ie6 and in both cases with 1.1 enabled the page is fine. Once 1.1 is disabled, the tell-tale script error appears." Since with our 1.0 vs 1.1 script change, squid is caching a version of the file that is gzipped, so if a 1.0 client asks, squid says oh ya, I have it, here you go (umm it's compressed and thus the end user receives an error.) Is there a way to have Squid vary the cache objects based on the incoming client HTTP protocol version? So that I can store 2 copies of any given file, one compressed and one not, and make sure Squid hands out the right version? Ideally, we need different buckets, per browser version would be awesome, based on how often broken software is released. It appears windows version 4-6 on XP (we think) has a bug where it unchecks the use http/1.1 box magically, not an end user selection but a defacto config from MS.. In fact we see some from IE 7 (not sure the standard user would go in and uncheck that for any real reason (I guess unless their IT department has a fubar proxy that requires it <shrugs>) Ideas? Yes 2.7, but trying to get an idea how stable folks think it is, as it's been noted it has more http/1.1 functionality. Thanks Tory
