ffproxy

ffproxy is a filtering HTTP/HTTPS proxy server. It is able to filter by host, URL, and header. Custom header entries can be filtered and added. It can even drop its privileges and optionally chroot() to some directory. Logging to syslog() is supported, as is using another auxiliary proxy server. An HTTP accelerator feature (acting as a front-end to an HTTP server) is included. Contacting IPv6 servers as well as binding to IPv6 is supported and allows transparent IPv6 over IPv4 browsing (and vice versa).

            Hi,

            ffproxy doesn't support http headers which size is > 2048 bytes, causing some web sites to return http 400 errors (bad request) to your browser.

            But it's easy to fix.
            You have to update 2 lines of code in request.c:

            line 188 : char buf[2048]; ==> char buf[4096];
            line 293 : char buf[4096]; ==> char buf[8192];

            and recompile with "make"

            Please note this is a quick & dirty fix, but it's doing the trick !!
