session timeout

[polilop]

Is there a way to see if the session is going to timeout and then warn the
user or display a page that it timed out

Set a clientside code timer that is reset on each new page and
that fires after less than 20 minutes.

Not ideal, eh?

Better warn them if they try something while no more in session,
that is while needing to login again an arriving there
not from the normal starting page.

This code seems to work good for me:

<div class="skeleton" id="timer" style="color:gray;font-family: Verdana;
font-size: 8pt">

</div>
<script language=javascript>
var dd=<%= Session.Timeout*60-2 %>;
var csptimeout=0;
function CSPstartClock(reset,timeout,whatdoc,towhere) {
if (reset) {
md=dd
}
if (md>0) {
time=md*1000
if (csptimeout!=0) {
clearTimeout(csptimeout);
}
csptimeout=setTimeout("CSPstartClock(0)",1000)
dhour=Math.floor((time%(60*60*1000*24))/(60*60*1000)*1)
dmin=Math.floor(((time%(60*60*1000*24))%(60*60*1000))/(60*1000)*1)
dsec=Math.floor((((time%(60*60*1000*24))%(60*60*1000))%(60*1000))/1000*1)
dsecDisplay = dsec.toString() ;
dminDisplay = dmin.toString() ;
if (dminDisplay.length == 1) {
dminDisplay = "0" + dminDisplay ;
}

if (dsecDisplay.length == 1) {
dsecDisplay = "0" + dsecDisplay ;

self.document.getElementById('timer').innerHTML=dhour+':'+dminDisplay+':'+dsecDisplay+' remaining until session timeout';
}
else {
if(timeout==null) { timeout='1790'}
if(whatdoc== null) { whatdoc=''; if(whatdoc=='')
{whatdoc='document.location.href';}}
if(towhere==null) { towhere='/osc2.0/osc_scripts/abandonSession.asp';}
mycounter = setTimeout(whatdoc+'="'+towhere+'"',1000)
}
md=md-1
}

CSPstartClock(1);

</script>
