I&#039;m trying to stop a password protected page reloading when the back button is pressed after the user has logged out and the form data is resubmitted (its not an original problem I know!). I came up with the idea of including the sessionID as a hidden field and comparing this field with the current sessionID in the check authentification include file.<BR><BR>This sort of works because the two values match when the user is logged in and they don&#039;t match when the user has logged out and has clicked backwards, refreshed etc. My problem is that using a simple comparison<BR><BR>If formref &#060;&#062; session.sessionID Then<BR>display message<BR>End If<BR><BR>doesn&#039;t seem to work, the values are the same but the script in the If is processed anyway.<BR><BR>Any ideas???<BR>
