Hi all,

I am bit confused about the technique to use for Chat Application integrated with current website.

I have got work to make Chat application integrated with Sql Server 2005.

I have decided to make use of AJAX Web Extensions control like ScriptManager, UpdatePanel & Timer for Periodic Page Refresh.

But the problem is how can i efficiently maintain log the online or offline users.

For an example, when user login into website i want to make log entry to the DB/Some XML file or some thing else.(This is where i m confused). This is similar to Gmail Chatting from Browser.

Any suggestion is highly appreciated.

Thanks in Advanced.
