Reverse HTTP proxy, load balancer, and SSL wrapper

Pound is a reverse HTTP proxy, load balancer, and SSL wrapper. It proxies client HTTPS requests to HTTP backend servers, distributes the requests among several servers while keeping sessions, supports HTTP/1.1 requests even if the backend server(s) are HTTP/1.0, and sanitizes requests. Pound proxies HTTO _and HTTPS requests simultaneously. In addition, it knows about failed back-end servers and can redirect requests according to their availability. It can run as setuid/setgid and/or in a chroot jail. Pound does not access the hard-disk at all (except for reading the certificate file on start, if required, and the pid file) and should thus pose no security threat to any machine. It needs at least the configuration file (read-only) and, optionally, the HTTPS server certificate (read-only).
