Stopping a backend process if user closes the browser window

hi,

I take the user input from UI in a jsp page and send the info to server, retrieve the data and generate a PDF file on the server and send that as temp file for user to be able to view it.
Now if the user closes the browser I need to stop the processing of the data in back end also
can any one please suggest how can I do that or find info to do that..

thanks

You could try using a session listener, assuming you have a link between the session and the process. You could also have a periodic Ajax call made from your page and if it stops being made the process ends.

hi,
I dont' have link between session and process.
I don't have much experience with Ajax either, can you suggest how it can be implemented or where I can find similar
implementations or something that give me an idea as how to implement that..

thanks

As far i know , you cant detect the browser window close event on server side . I guess David mentioned about session-time out
