   Proloxy sample configuration file.

   This simple example file contains 2 clauses of request_prefix_target/3.

   The first rule relays URIs that start with /rits to a (RITS) server
   on port 4040.

   The second and final rule relays all other requests to a different
   web server on port 3031.

   The order of rules is significant, because Proloxy commits to the
   *first* rule that succeeds. In this example, if the order of rules
   were exchanged, all requests would be relayed to port 3031.

   Rule 1: Provide access to a RITS server via the prefix /rits.
   For example, accessing http://your-url.com/rits/demo.html
   fetches /demo.html from the RITS server running on port 4040.

   The prefix (second argument) is also /rits, so that redirects from
   the RITS server are rewritten in such a way that the following
   client request is again correctly delegated to the RITS server.
