ffproxy

Filtering HTTP proxy server

ffproxy -- Fast Filtering Proxy, is a filtering HTTP/HTTPS proxy server. It's capable of filtering by host, URL, and header. Custom header entries can be created for filtering. It can also drop privileges and optionally chroot(8) to a chosen directory. Logging to syslog(3) is supported, as is using another auxiliary proxy server. An HTTP accelerator feature (acting as a front-end to an HTTP server) is also included. Contacting IPv6 servers as well as binding to IPv6 is supported which allows transparent IPv6 over IPv4 browsing (and vice versa).
