Re: [squid-users] Caching and tracking or 2-level cache rule?

What you describe cannot easily be acheived using Squid, but you may be able
to do something close to it by using a redirector which performs the tracking.

Also, using Session URL's generally totally screw up caching, as caching is
performed on the URL as a whole. There is no way Squid can know that the
"/SID/" component of the URL is not actually part of the URL. You can use a
redirector to remove the /SID/ component, but then it won't get forwarded to
the origin servers either except as part of Referer...
