RE: [squid-users] Same Domain Caching

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

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.
