Hi David > In section 508, Provision P) calls for a warning when a session is about to > expire giving the user an opportunity to get more time in the session.

What I am about to say only applies if pages are being generated by a script or programme: If I were being asked to do this, I would probably use a REFRESH in the header; this would cause the same page to re-load at a set interval, checking on each load how much time is left. When the critical time were reached, I would switch on a warning message when the page is re-drawn. Possible problems: I don't know how this would work with screen readers. Another alternative is Server Side Push; I mention this out of interest only because I believe that it is only supported by the Netscape browser family. Practical suggestion: rather than warning just before a session is about to expire, state somewhere that "your session will expire in xxx minutes unless you do xyz."
