Hi,

In my project a user can comments post articles and I am done with that, but I am stuck at a crucial point.
I would like that a user must be logged in website before he is allowed to post anything. If he wants to post anything he must be logged in.
How to check it whether user is logged in or not?
If he is not logged in then he is directed to login page and if he is already logged in then he is directed to page that he was using. How can this process be carried out?

Please guide.

If possible please provide a small example.

By maintaining Users login details into "Session".

Have a look at below links for more information on "ASP.NET Session State Overview".
