Prevent a user from visiting certain pages until registered
<p>I am developing an ASP.NET website. There are some pages on my sit that I want him to see only if he is a registered user. If not, he should be redirected to the appropriate page. Should I be checking this on the Page_load event that the user is  logged in or not?</p>

<p>If the user types the name of the URL, this would still work, right?</p>
