Squid-2.5 in it's base distribution can't rewrite Location response headers, but the rproxy patch from devel.squid-cache.org adds this functionality if needed. Just as Apache, Squid is not capable of rewriting URLs within the content of the returned response. If possible it is always best to ensure there is no rewrites of URLs taking place in the accelerator. This will considerably reduce the administrative burden even if the proxy does support full rewrites of even returned content. Have customers doing this with a custom proxy similar to what you describe below, and the rulesets quickly grows quite large and very hard to track any errors.. not to mention performance penalties from either having to buffer the whole response before replying or disabling the use of content-length (which kills persistent connections). > ability to rewrite page content.

And Squid will happily accelerate this rewriting by simply providing the Apache server as the origin server for Squid. So you have "Internet -> Squid -> Apache content rewrite application -> Origin server". Or if you can make the origin server behave and use the same URLs as the client then just "Internet -> Squid -> Origin server", without any redirectors/rewriters of any form. > > 2.

Yes, Squid supports multiple sites in accelerator form, and the content rewriting is outside Squid as an origin site or peer proxy in the eyes of Squid so you can have as many of these as you please.
