HAproxy 1.4.2

HA-Proxy is a TCP/HTTP reverse proxy which is particularly suited for high availability environments. Indeed, it can :

• oute 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
