RE: [slightly OT] cache refusal problem with IE, http headers

I know this thread is rather lengthy, and took a few turns along the way, but I ran across this link the other day and thought it might be of use for everyone on the list - it's an official explanation of how IE handlers caching via headers. there's also a few links in it that are worth noting

I saw your header, but couldn't tell that it was for tomorrow, with the GMT time zone info. I don't read GMT go figure ;) What I would recommend is trying to match the headers exactly as when serving up the static file since we know that works, oh and make sure the file extension is the same

Re: [slightly OT] cache refusal problem with IE, http headers

OK, did it the hardway: after a lot of tcpdump -i -s 500, grepping and stringing, I tackled it. Halfway. IMHO, it boils down to both a IE bug and a somehow 'hidden' feature of Apache. It seems that on script execution an extra header "Vary: Host" is sent to the browser. This is what the RFC's
