%description
HAProxy's Proxy Protocol is a way for upstream proxies and load balancers to
report the IP address of the original remote client to the downstream server,
without having to modify things like HTTP headers in the actual payload.
This package contains an Apache module that implements the downstream (i.e. the
receiving) server side of this protocol, thereby allowing other modules to see
and use the actual client's IP address instead of that of the upstream proxy or
load balancer.
