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? > > Perhaps you didn't understand that these are our sites, squid is acting > > as an accelerator.

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). > But you may want the overlapping request support available > in squid-3 or as patch to 2.5 (part of the cerberian patch) > If you look at the patch this is what is already done to remove # html anchors from urls so nothing new. -- Jose Celestino | http://xpto.org/~japc/files/japc-pgpkey.asc ---------------------------------------------------------------- "You just have to accept that some days you are the pigeon, and some days you are the statue." - David Brent
