XLB is an HTTP load balancer. It features
connection management where requests are parsed
and assigned to a persistent connection to the
back-end server. This reduces back-end server load
by causing fewer forks, less memory use, and lower
CPU consumption. It can decode SSL requests, which
is useful if you have an SSL accelerator board.
Scripting allows requests to be routed to specific
pools or headers modified based on the URL,
filename, source IP, and other fields. A fast
in-memory cache is included .
