What u do once login save some staus in session variable.

and in Login page , OnLoad event just check for that session variable status , and redirect it to perticular page

session["loggedIn"] = true;

if(session["loggedIn"] = true)
   Response.redirect("~/desiredpage.aspx");

Simply put this javascript between your <head></head tags, and you're done:

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

hi hiren

hi there

there are servel options

1) Use Sessions so as soon as you logout your session will get expire,now if user presses back
   he/she must be redirected to login page

2) use javascript History class it has some usefull functionality like
   History.Clear

3) use Response.Expires=-1 it will erase all cached pages

i hope that would help you out

You Can Use Session For Global value.


When You Open Your Home Page Or Main Page You Have To First of All Set Your Session As "0", Means User Not Logged In.
Session("Login") = 0;
After That Check Condition


After Login By User Set It As "1".

Session("Login") = 1;

If (Session("Login")==0)
         MsgBox("Please Login.")     //Means User Till Not Logged In.

When User Will Press On Logout Button Then Again Set it As "0".

Session("Login") = 0;


So, After Logout When User Will Press Back button It Will Ask Agian For The Login...



//It Will Work 100%...
