Ok, I see. But not that either. That's what the clicktag does client-side.

But that's just an example. People tend to do things just because they know
they can, for instance I have this on just a few minutes logging:

# grep \? cache.log | grep URI | grep '/css/2004/hp/hp2.css?nocache' | wc -l
1328

Well this file hasn't been changed since Mar 15 2005 so what's the point?

From what I've read redirectors are somewhat of a slowdown. Haven't used them
myself but the scenario is of an ISP with over 800 req./second sustained
so I'd like something light.

And, from my understanding, redirectors just rewrite the request to the end
server to something else, they have no influence on what is or is not cached
(maybe I got this wrong) and what got me to this is that I have tons of these
requests and having HITs from them would be a major performance boost (that's
why I have squid there in the 1st place).

If you look at the patch this is what is already done to remove # html
anchors from urls so nothing new.
