Added reverse proxy support from Kim Holviala. His comments regarding
this addition follow: The patch implements a simple reverse proxy (with one funky extra feature). It has all the regular features: mapping remote servers to local namespace (ReversePath), disabling forward proxying (ReverseOnly) and HTTP redirect rewriting (ReverseBaseURL). The funky feature is this: You map Google to /google/ and the Google front page opens up fine. Type in stuff and click "Google Search" and you'll get an error from tinyproxy. Reason for this is that Google's form submits to "/search" which unfortunately bypasses our /google/ mapping (if they'd submit to "search" without the slash it would have worked ok). Turn on ReverseMagic and it starts working.... ReverseMagic "hijacks" one cookie which it sends to the client browser. This cookie contains the current reverse proxy path mapping (in the above case /google/) so that even if the site uses absolute links the reverse proxy still knows where to map the request. And yes, it works. No, I've never seen this done before - I couldn't find _any_ working OSS reverse proxies, and the commercial ones I've seen try to parse the page and fix all links (in the above case changing "/search" to "/google/search"). The problem with modifying the html is that it might not be parsable (very common) or it might be encoded so that the proxy can't read it (mod_gzip or likes). Hope you like that patch. One caveat - I haven't coded with C in like three years so my code might be a bit messy.... There shouldn't be any security problems thou, but you never know. I did all the stuff out of my memory without reading any RFC's, but I tested everything with Moz, Konq, IE6, Links and Lynx and they all worked fine.
