Take this pac file: $ curl http://wpad.wws.lan/wpad.dat function FindProxyForURL(url, host) { // simple hostname if (dnsDomainLevels(host) == 0) {return "DIRECT";}
// match Host against local domains (w/ optional :port) var dom = /(127\.\d+\.\d+\.\d+|\.wws\.lan\.?|\.local\.?)(:\d+)?/; if(dom.test(host)) { return "DIRECT"; } // All other requests go through port 8080 of proxy // should that fail to respond, go direct: return "PROXY proxy.wws.lan:8080; DIRECT"; } Obviously the browser needs to evaluate the URL each time it wants to make an http request. So I want to do that in my proxy. Currently proxy chaning in mod_proxy supports only say: ProxyRemote * x.y.z.w Now not having found mod_proxy can help me in that, I thought about writing a mod that in apache would interpret a pac file. In my configuration, the browser can not be aware of the pac file, only my proxy. I tried to explain you what was my project doing, instead of asking how override the connection to a server. if this is not a subject of interest of this group, I do apologize for having misunderstood the aim of it. However I still don't understand why this should be offtopic. Giovanni PS: I couldn't figure out a way to search into archives from http://mail-archives.apache.org/mod_mbox/httpd-modules-dev/. I used google "site:" option, and found no entry for "pac" or wpad.
