Why a double question? When I use "Shift-Reload" with by browser, it
sends a HTTP request with "Pragma: no-cache" header... However, ignoring
"Pragma:no-cache" is impossible at the moment (without patching squid),
right? So a request with that header set *always* makes squid ask the
origin server?

(Ehm, I forgot to say, that I am running squid as a transparent reverse
proxy for an always overloaded application server :-).

In this case the origin server had to be asked always. This is
ok, I only don't want cached content to be fetched more often
then really necessary from the origin server.

I see, thanks!
