Browser Close Event

[raghunath.asha]

Is there any way in JSF/Richfaces to know the browser close event (forced by user) using PhaseListener or something?

My problem is I am doing a download file from my application and it was showing of the % downloded etc...If the user closes the browser before completion my application is still doing the process in backend.

Then again user opens another session/browser, the ajax push is showing the previous and current % downloads and making confusions.

So If I know the session kill/browser kill event I can do some logic in the backend to stop/cancel downloading for the killed session.

Any thoughts...

Hello,

Take a look at this: http://msdn.microsoft.com/en-us/library/ms536973(VS.85).aspx

thanks for reply Laevsky,
unfortunately onunload gets called when the client refreshes the page too so we can't be sure :).

BTW, session is dead when user closes the browser and then opens it again. Are there any problems with this?

Thanks Laevsky. Unload option work out pretty much well. The remaining concern is regarding the unused session, in case of browser close operations. I do have a custom object representing a Session, and want to invalidate and remove the object from internal memory if user closes the browser.

Is there a way to know if a session "dead" or "alive" by inspecting any of the RichFace object? Or should I use an idle period logic inside the application logic?

No, there is no way to know that. Application server will clear unused sessions internally, so you do not have to do that explicitly.
