See refresh_pattern in squid.conf for the automatic procedure Squid uses
in determining if it needs to ask the origin serverif the page has
changed or not.

If the browser is sending correct information to Squid:
* "Reload" forces Squid to ask the origin server if the page has
changed.
* "Shift-Reload" forces Squid to download a new copy from the origin
server, even if it seems that the page hasn't changed.

Netscape does this correcly. Internet Explorer is known to not do it in
some situations, especially if you are running a proxy which
transparently intercepts port 80 traffic ("transparent proxy").
