Log off user if they forget

Here is whats in my "application.cfm" file I cant seem to figure out what else I need to add to it to monitor something like page request. So if a user forgets to log out then the application will realize that they are gone and log them out automatically.

<cfapplication name=""
               clientmanagement="" 
               clientstorage="">
              
<!--- Initialize application varibles --->
<!--- The variable are all client variables --->
<cfparam name="client.    " default="">


<cferror type="exception" mailto="me" template="exception.cfm">

<cfset REQUEST.sitename = "name">
<cfset APPLICATION.companyname = "name">
<cfset APPLICATION.dataSource = "dsn">
<cfset dbdsn = "user"> 
<cfset dbuser = "user">
<cfset dbpw = "password">



<cfmodule template="header.cfm">

Code (markup):

Adding sessiontimout does not seem to work. Or maybe I set it up wrong.

 

Hi,
Are you saying this doesnt work ??

<cfapplication name="myapp"
sessionmanagement="Yes"
sessiontimeout=#CreateTimeSpan(0,0,45,0)#>

 

I think thats what I'm saying, Where I may be confused is, When the session times out does that clear all the cookies from the clients computer as well?

When I tried using session timeout I don't think i got the desired result because I have no session variables to time out.

Thanks for you response.
