Also if i copy the url and paste the url in another page the home page is being getting accessed. i want to prevent the accessibility if any body paste the url by copying the url and pasting it in another internet explorer rajsekhar

Yo! Use session variables to store the login details of the user. And when your home page loads, check if these session variables have acceptable values, if not, redirect to login page... M :)

What marky777 said is right. You should use one Session variable in your basepage. You should check whether this is authenticated user or not. Since the code is written under basepage, it will automatically check the user in each and every pages' load. Some people use Cookie to handle that thing instead of Session.
