Hi all, I've setup squid to proxy everything to a single server I have. Based on a header, I might want to serve a different version of a file for example for: X-MY-HEADER: 1 URL: /css/style.css Would not be the same as: X-MY-HEADER: 2 URL: /css/style.css Ideally though I'd like to be able to cache both. Can I get squid to somehow differentiate based on an incoming header? Failing that, I'm generating an etag on the server that's a hash of the content. Will this be enough to distinguish between the different files? Thanks Tom
