IIS - how to close my page on internat explorer in asp.net web application

Hi expert
I have run a web application in asp.net with back end sql server 2008
my problem is that i want to close my page automatically after 1 hours for that i have manage task Scheduler.
i have written following line of code

 foreach (System.Diagnostics.Process exe in System.Diagnostics.Process.GetProcesses())
        {
          if (exe.ProcessName.StartsWith("iexplore"))
            exe.Kill();
        }

but this code is running on local server but not running on iis server.

http is a disconnected protocol.  Your code here is attempting to kill a process on the server not the client's PC.  The browser must execute the close request.  It cannot be done with server side code.
