 It's a good idea to limit access to the local machine and whatever IPs your debugging from.

+Notes from ScottKelley
+
+
+  I have a slightly more complex setup than illustrated (Vignette Portal v4 running on Websphere v4).  I don't have the luxury of all the static images being in one place.  I use a few more mod_rewrite rules and a server map that I cribbed from some other examples.  While not the most elegant, it does work for us.

+The server_pool.conf file looks like. These addresses are actually hardware load balanced to many boxes.
