I've implemented a JS based timer into our intranet. You shouldn't need
frames either. I define the variable "session.StartTime" to whatever my
Application timeout is. So the code below will fire a dialog box 2
minutes before a timeout. It works for me, although some users have
told me they never see it. Try it out and let me know...
<cfif isDefined("session.StartTime")>
<script language="JavaScript"><!--
//-- Variable below defines how many seconds to wait.
var howManySeconds =
<cfoutput>#Replace(NumberFormat((session.StartTime-2) *
60),',','')#</cfoutput>
//--This is the function that pauses, then calls our function below.
function pause() {
myTimer=setTimeout("whatToDo()",howManySeconds*1000)
}
//-- Let's notify the user their session is about to time-out.
function whatToDo() {
alert ("Your session is about to time-out. Please save anything you
may be working on.")
}
//-->
</script>
</cfif>
