this code will expire your page....

Code:

<% Response.CacheControl = "no-cache" %>
<% Response.AddHeader "Pragma", "no-cache" %> 
<% Response.Expires = -1 %>

Put rokslide's code at the very top of any ASP page you want to expire (in your case, the page you want to expire if the user clicks "Back"). It should be before anything is written to the browser, so ideally, it should be the very first thing in your ASP script.

You need to put it on the previous page.. the page they would go to if they click the Back button. All you're doing here is expiring the current page.

You can also try:

Code:

<%
Response.AddHeader "Expires", DateAdd("d", -1, Now())
Response.AddHeader "Last-Modified", Now & " GMT"
Response.AddHeader "Cache-Control", "no-cache, must-revalidate"
Response.AddHeader "Pragma", "no-cache"
Response.CacheControl = False
Response.Expires = -1
%>

it needs to go before your include I would guess....

<%@LANGUAGE="VBSCRIPT" CODEPAGE="1252"%>
<% Response.CacheControl = "no-cache" %>
<% Response.AddHeader "Pragma", "no-cache" %>
<% Response.Expires = -1 %>
