HAProxy is a TCP/HTTP reverse proxy which is particularly suited for high availability environments. Indeed, it can : – route HTTP requests depending on statically assigned cookies ; – spread the load among several servers while assuring server persistence through the use of HTTP cookies ; – switch to backup servers in the event a main one fails ; – accept connections to special ports dedicated to service monitoring ; – stop accepting connections without breaking existing ones ; – add/modify/delete HTTP headers both ways ; – block requests matching a particular pattern ;
