How can I know ,connected user to the
internet or not?
Ahmm, I think you should specify your question a little more. Maybe you have a better chance to get a qualified answer then.
I am assuming that you want to know if your user is connected to the internet or not ...
I would try to get the HTTP headers from a known stable server (www.sun.com, www.cnn.com) ... if you get the headers, they are online, if not, they are not ...
you may want to try one or two different servers if the result is negative, just in case the server is down.
Hope this helps
