Your code example contains a mix of HTML and Perl, what's up with that?

Now even after this, if i click the browser back button, the session still exists. I'm able to view the Page2.

Are you sure the browser isn't just showing you a cached version of the page? Many modern browsers now have "web developer tools", which you can use to see if your browser is actually making a request to the server or not. In any case, you can get your CGI script to kindly ask the browser not to cache the page, see e.g. here.

If you find that the session really does still exist, then have a closer look at the documentation and other threads on this matter. For example, you may want to call $session->flush() after delete; other places suggest that simply $session->clear() is enough - note that a session existing is not necessarily the same as a user being logged in within that session.
