You have stated a lot of things that you need to do.

What are you having problems with?
What are have you tried so far to solve the problem?

If you are looking to end a user's session then you can use the Session.Abandon Method to abandon the session that the user is currently working with....

You can set the Session to expire automatically after a given time using the web.config for the site.

Or you could store the time that the user logged in into Session and every time the page is loaded you want to compare the login time in Session to the current time to see if their time has finished.

In order to do things client side you probably also want to store the login time into a HiddenField so that you can access it from JavaScript.

You should also store the login time into the HiddenField so that you can access it in JavaScript as well.

You would then want to use the JavaScript setinterval to create a timer for when to display the message.

Be aware that the user's clock may differ from the server's clock and therefore you're going to want to store both the login time and the current time into HiddenFields to try and synchronize this as much as possible....

You can look into Session timeout.

Also for certain pages, you can check whether session is valid or not. If not then redirect. This will only happen when the user will request/ post some data to the web server.

actually i want to redirect to page after finishing the time without posting any data to server
.as you see in online exams a person is automatically log out after finishing the time .in this i want to add specific time for specific user.this is all i want .simply
i want to develop a site in which a user can work untill his time expires and after expiring he will be redirect to a page . and time for persons tp access site will be differ
