[squid-users] Reverse proxy multiple sites with re-writing
Hi, It's been a long time since I used squid - late '90s to proxy an entire organisation's internet access over a 33.6k modem! But I digress... I'm working on a targetted google/yahoo ad system. For the sake of illustration, assume that Pizza Hot is a Pizza company with a website at pizzahot.com and that my company's website is adcounter.net. An ad. campaign would aim to get links for Pizza Hot at the top of search engine results. Instead of a link to pizzahot.com, the link would be a link to pizzahot.adcounter.net. The idea is that pizzahot.adcounter.net would be served by a squid instance which would serve up content from pizzahot.com, re-writing certain key parts (telephone numbers, some URLs, etc.). I have a couple of questions: 1. Can squid do content rewriting? 2. Would it be possible to proxy multiple such sites on one squid host? R.

I'm not sure that it can rewrite the URL in accelerator mode. Apache can rewrite the URL using mod_rewrite; however, it doesn't inherently provide the ability to rewrite page content. Instead of using mod_proxy to return the retrieved content to the requestor with the rewritten URL, you would want to use mod_php, mod_perl, mod_python to implement a routine to scan and rewrite the page content. 2. Would it be possible to proxy multiple such sites on one squid host? I don't know. I use Squid in its basic form to support client browsers. I use Apache and mod_rewrite to implement a service similar to Squid's accelerator mode and to provide SSL encryption between the security perimeter and the browser. Of course, I could be all wet as I haven't really looked at the changes in Squid since the late Nineties. Merton Campbell Crockett [EMAIL PROTECTED]

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.
