can anybody help!!!!

how can i use session in all my page, wherein the user can not view the previous page. or when the user click on the back button he/she can not view it.

thanx

Does the user already logged out from the access page? If he/she does, then put these codes on top of every pages.

<%
If Session("access_user" = "" Then
Response.redirect "invalid.asp"
Else

%>

<!-- HTML -->

<% End If %>
