I'm the sysadmin at a University. Our students looove youtube! I wanted to cache youtube content - some of these files are 5-50MB .. so the savings would be great. However I have run into a problem that would affect the efficiency of my cache...
Apparently youtube uses multiple servers (with different hostnames) to serve the same content. For instance, http://lax-v87.lax.youtube.com/get_video?video_id=kEysFttcIkE is a 8MB flash video. And http://lax-v88.lax.youtube.com/get_video?video_id=kEysFttcIkE is the same video. I would like to tell squid that it should consider hosts of lax-v[0-9]*.lax.youtube.com to all have the same content. If they only had one or two servers, I wouldn't care so much - but they have presumably hundreds. If their site tells my clients to go to a randomly-assigned host to get the content, I'd rarely get any cache hits. I'm still reading through the documentation and FAQs.. but I'm not exactly sure what I'm looking for.
