I had considered doing that as well - using a redirector to match on youtube.com/get_video but then I'll need to save those to the disk and manage them myself as opposed to using squids method. Is there a successful use of ETags for something like this / is it worth looking at? As I understand it that's essentially there point (if used correctly) ? Something else that might be worth looking into (for me) is whats after the ? - I suppose that if it in some way identifies the video I could rewrite the url to be the one I know is cache (e.g. the first ever request for that) Thanks again for the help Dave -----Original Message----- From: Adrian Chadd [mailto:adrian@xxxxxxxxxxxxxxx] Sent: Monday, October 22, 2007 9:38 AM To: Dave Raven Cc: squid-users@xxxxxxxxxxxxxxx Subject: Re: Same Domain Caching On Mon, Oct 22, 2007, Dave Raven wrote: > Hi all, > Is there a way to assume that anything under a certain domain is > similar across servers?

There's been a few attempts at it but noone yet seems to have implemented what I've suggested. Someone recently posted how he does it via log post-processing and rewriter rules. Adrian
