How do I make a user log out of a site... and if another user uses the back button to go back into the site, it shows a 'Page Expired' page instead of the website?
I used a <cfinclude template="CheckAuthority.c
<!--- CheckAuthority.cfm --->
<cfset bLoggedIn = False>
<cfif IsDefined("Session.Login_I
<cfif Session.Login_ID neq "">
<cfset bLoggedIn = True>
</cfif>
<cfelse>
<cfif IsDefined("Cookie.Login_ID
<cfif Cookie.Login_ID neq "">
<cfset Session.Login_ID = Cookie.Login_ID>
<cfset bLoggedIn = True>
</cfif>
</cfif>
</cfif>
<cfinclude template="myErrorPage.cfm"
<cfexit>
</cfif>
<!---- CheckAuthority.cfm End --->
And whenever a person logs out, I bring them back to index page which contains:
<cfset structClear(session)>
<cfcookie name="login_ID" value=0 expires="NOW">
It's supposed to display an Error Page if they are not authorized to access the page. But somehow it doesn't work. Although the error page did appear, it also goes on to show the rest of the protected pages. It seems that the <cfexit> function did not do the trick.
Can someone please help or suggest a better way to do a logout function? Thanks!

just a hunch.. try putting
<CFHEADER NAME="Expires" VALUE="Sun, 06 Nov 1994 08:49:37 GMT">
<CFHEADER NAME="Pragma" VALUE="no-cache">
<CFHEADER NAME="cache-control" VALUE="no-cache, no-store, must-revalidate">
in ur application.cfm.. this might make the page get a fresh copy and not use the cached copy..
cheers

Hi,
the "page expired" page cannot be controlled by u - its the browsers property which tell the users that the browser cannot get the page from the cache as it was a result of a form submision / db interaction & it needs the submitted values to show the page [mind u - this is not a error on the site - so chill abt this]
I see that while logging the user in - u chk for the session & for logging the user out - u r using cookie ... ???
do one thing - use only one of them - dont use both.
& if ur using both - make sure u expire both on logout - so they cannot access the pages once they log out.
+ u'll also need to use the CFERROR tag in ur application.cfm file to display the error pages in case some error occurs on ur site.
OR
u can use the CFAdmin & set the default error template in the administrator s- it can handle everything for u
let me know ...
K'Rgds
