Check connected to internet

Can someone suggest the best way of checking if I'm connected to the internet, or a specific web server?
Is it just a case of trying to get a response from a given web server and checking it's equal to 200 so I just need to use the URLConnection class? I'm just concerned with having to wait for a response if the server is down or a route is unavailable.
Ideally, I want to write a servlet that supplies a working route to a caller.

Well, there is no easy way to do this. One of the things you can do is by pinging remote servers. I suggest to create a simple class that does socket connection, and ping more than one server, since a site could be downed.
I agree. Here's the link:
