Not possible. Squid-2.7 does not support enough HTTP/1.1 features to
cache all content properly. Upgrade to a current release of Squid.

I'll bet. The * means that the URL represents multiple different
versions of the object being delivered, which one is in this response
depends on something outside the HTTP request used to fetch it. There
is no way your proxy can identify or replicate that variance decision.

Example; the chrome D/L server may be delivering .exe containing
built-in translations based on your personal account G' preferences.
 How would you like to find an automated upgrade made your browser
suddenly display only Klingon because the first person going to update
through this proxy was a Trekkie ?
