Add two new modules to handle load balancing across multiple apache servers within the same datacenter. mod_heartbeat generates multicast status messages with the current number of clients connected, but the formated can easily be extended to include other things. mod_heartmonitor collects these messages into a static file, which then can be used for other modules to make load balancing decisions on. This module was originally written at Joost by Sander Striker, Justin Erenkrantz, and myself. We have been given permission by our employer to contribute this module.
