Possible to monitor URLs an application is connecting to? I'm relatively new to the wondrous world of Apple and Mac OS X so please bear with me..

I have an application which I would like to see which URLs it is "connecting" or "communicating" with. 
Is that at all possible and if so, I would be very glad to be pointed in the right direction.

A firewall that can alert you when an app connects to a certain domain, and lets you allow/block the connection.



Alternatively, you can allow all connections and just monitor them.
