I have an application that, after 20 mins of idle (detected
by JS), the user is given a warning saying they are about to
be logged out with a link to keep the session going. My
original plan was to sent an AJAX request to a page when the
link is clicked, but I have read that an AJAX
Just off the top of my head and without doing any research into the topic.
Assuming everything you said is accurate, that you can't sustain the session
with an AJAX request, when your user clicks the link, it could load a 1px
x1px iframe into a div on the page that loads a keep alive page, thus
I have read that an AJAX request will not keep the session alive.
Where did you hear that? If the Ajax request is to a ColdFusion page
that is part of your application it will most certainly keep the session
alive. The server, after all, doesn't even know it is an Ajax call.

Server:
If you have a session going and it is idle up to the timeout it will end. As
soon as another request happens after the timeout, a new session begins. If a
request occurs before the timeout, the countdown begins all over again.
Client/browser side:
Seems like you need to write

I was wondering ... if what I read was wrong and you actually can keep the
session alive with an AJAX request.
This is the case.

Bobby,
1) I absolutely REFUSE to use a frame or Iframe whatsoever.
Then you like making life hard. ;) While an frame would be the most
compatible, and IFRAME should really work in every modern browser (doesn't
work in Netscape 4, but if you need that you could use an ILAYER tag for
NS4.)
setInterval(document.images['session'].src='image.cfm';,600);
This will keep the session alive...

You're right. Have a look at XMLHttpRequest in Javascript.
You can call a CF template every 10 min or so, directly from a script,

no blink, no glass cursor, no nothing. The user will see

Probabily, although AJAX may be a big word when only a couple of lines

Bobby,
Just out of curiosity... can a frame trigger a js event in another frame?
Provider there are the same domain (which is usually the case,) yes. Just
use the parent object to reference the document object that created the
iframe /.
Just curious since I still refuse to use one :)

Ive got a js routine that does just this.
Basically you set it to a minute less than your session timeout. If
it expires, it reloads the page they are on. Just dont want to use it
with any pages that you post to.
Let me know if you want it.

so if they are in the middle of typing War and Peace in a form field when
the JS kicks off, they lose it all?

Why not use a frame or an iframe to load a page on the server in the
background? This way they won't have to lose the current

the site, and that is all that's required to keep the session active.

Well if you use an iframe, you can set it to a page that reloads every few
seconds (minutes). No javascript needed, just META REFRESH. Same with
Frame. But Frame would require you to build your site using frames (yuck).
