SUMMARY = "TCP/HTTP proxy and load balancer for high availability environments"
DESCRIPTION = " \
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 load among several servers while assuring server persistence \
   through the use of HTTP cookies \
 - switch to backup servers in the event a main server fails \
 - accept connections to special ports dedicated to service monitoring \
 - stop accepting connections without breaking existing ones \
 - add, modify, and delete HTTP headers in both directions \
 - block requests matching particular patterns \
 - report detailed status to authenticated users from a URI \
   intercepted by the application \
