Javascript isn't working in ASP.NET

Question

How to move user forward & backward when user is logged in & when he is logged out ,he won't be able to go it's home page .

I'm creating a website in ASP.NET (Framework 4.0). I had used Javascript in Masterpage head section. Code as follows.

<script type="text/javascript">
        window.history.forward(-1);
    </script>

And on page load (masterpage ) i had written code for cache.

Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.Cache.SetExpires(DateTime.UtcNow.AddHours(-1));
        Response.Cache.SetNoStore();

My user gets login to his home page (i.e frmUserHome.aspx ) when clicks on next page (i.e frmUserService.aspx) he is redirected to service page ,but he is not able to go back to it's home page (i.e frmUserHome.aspx). This all is happening beacause of javascript written in master page.

The below Javascript code may help you...

<script type = "text/javascript" > 
    function preventBack(){window.history.forward();} 
    setTimeout("preventBack()", 0); 
    window.onunload=function(){null}; 
    </script>

use this code in a page where you don't want to go back...
