Hi, We operate a reverse proxy cache for thousands of domains and this works quite well. The problem we have is that our cache has to be very big (too big for memory) so we rely on some disk cache to serve alot of this. Our cache objects are like: www.somdomain1.com/common/some.css www.anotherdomain1.com/common/some.css where some.css is the same file - but Squid sees these separately and caches them separately causing our cache to fill up inefficiently. Is it possible with Squid to cache this common object once. It isn't feasible to have common elements served from a single domain (i.e. www.somedomain1.com/ can't pull in content from www.our-common-cache.com/common/some.css) What I'd like to be able to do is tell Squid these are common objects and therefore when it sees these, serve from a "fake" domain internally to it so it is transparent to the backend web servers, yet other elements are served as normal. Is this possible? The net effect would be thousands of separate objects being cached once allowing us to serve our cache from memory again.
You need the storeurl_rewrite feature. So far only available in Squid-2.7. http://www.squid-cache.org/Doc/config/storeurl_rewrite_program Amos
