[Mono-dev] WebService request Timed out

If it is truly the case that a mono webservice must be able to access 
itself by the url used to call it, then the simple solution is the 

Use a DNS hostname which resolves to the public IP of your NAT router.

Forward port 80 to your xsp/apache server.

Put the hostname into the hosts file on the xsp/apache server, but use 
the server's private IP or loopback address.

Although I would be interested to know where you found information 
stating this to be the case. My guess is that there is something else 
going on.
