title: How to clear Session when navigating away from one page
body: <p>I googled this about 1/2 a hour no hit's. Scenario is that, dynamic scripts are saved in string builder whose <code>"string"</code> representation is stored in session. It just happens that when user navigates away from one page to another the script[from session] gets registered using <code>"RegisterStartupScript"</code>. The script is registered in PreRender event of the Page. So i would like to clear this script in session while the page navigates away btw rule out a option to create another session variable and clear previous one. It's a overhead :(</p>
