Connection to what kind of server?

Most of the time, the only way to "check the connection" is to try and connect and see if it comes back with any exceptions.

OK, so the only way to know if the connection is going to work is to connect and handle any exceptions that get thrown. It's pretty much a waste of time to do anything different. Just because a connection works one time does not mean the connection is going to work 10 seconds from now.
