Have you searched the list archives? This has been discussed many times before. The consensus answer is that there's no easy way to do this (remember, HTTP is a stateless protocol), and you're going to have to rely on a timeout mechansim to at least some degree. If there is a security issue, you'll have to make the timeout short. The best approaches to doing this involve applets and/or javascript, but for a variety of reasons, they still won't get you 100% coverage. > Albert Pi wrote: > > >What's the reason you want do that ? > > > >Albert Pi > >Corp IS System Delivery > >516-803-3762 > > > > > >>>>[EMAIL PROTECTED] 09/09/02 06:42AM >>> > >hi, > > > > can anyone have an idea about this. > > > > how can i check or get notified on my servlet if the client browser > >has close? > > also when my session has timeout? > > > > is there any event notification that my servlet would receive or i > >have to check > > it manually? > > > > i'm using Tomcat 4.0. > > > >thanks > > > > randie > Milt Epstein Research Programmer Integration and Software Engineering (ISE) Campus Information Technologies and Educational Services (CITES) University of Illinois at Urbana-Champaign (UIUC) [EMAIL PROTECTED] ___________________________________________________________________________ To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff SERVLET-INTEREST".
