Those would be the port numbers methinks. If I'm not mistaken, it'd be typical to establish a connection to a web server on port 80, but the data transfers would go over a high port. Otherwise you'd only be able to have one client connected to the server at any given point in time. But I could have that all wrong. -- ¶ One·should·only·use·the·ASCII·characterset·when·compos » ing·email·messages.

A socket is a unique pair of (IP,port) pairs. So you could only have one connection to www.example.com:80 from client.example.net:6363... but you could also have a connection from client.example.net:6364, as well as from foo.example.org:6363 or anything else. -- Brian Moore | Of course vi is God's editor.
