Closing the browser

[Reeti Saha]

Hi:
I'm using jsp for my web based project. I've written code for some clean up operation when a button is pressed..but I want the same method to be executed if a user closes the browser window also.
Pls. let me know how to proceed.
Regards
Reeti

Far as I kow, you will have to use javascript.
The window.close() method

But realize that you're not GUARANTEED that this method will be run whenever someone closes your browser window... what if they simply type a new URL into their browser? What if the browser doesn't support Javascript, or they've turned it off?
Make sure your session.setMaxMaxInactiveInterval(int) is set to an appropriate period so that its long enough so it doesn't kill people's sessions who are just slow while surfing around your site, and its short enough to invalidate people's sessions who have left your site without logging out.

One of the most common ways *I* close my browser is by abnormally terminating the program (yes, you can tell I use Netscape - still waiting for Microsoft to do a native port of IE for Linux ).
Try catching *THAT*

It depends on the browser you are using.
close is an event just like leftClick or rightClick. You'll have to code the close event for each browser you want it to work on. Once you have identified how to capture the event, it's just a matter of having the javascript function take the browser to the page that does the clean up before it closes.
I expect it will be a bit tricky but it should be possible.

Hi Reeti,
You can try this method.
On the unload event of the window (this will happen when the user closes to window), call a javascript function which opens a new window and loads a JSP which does all the cleanup. This window can be automatically closed, once the required task is done.
This seems to be unconventional approach but will definitely address your problem.
This won't solve the problem like if somebody switches off the computer or network go hay-wire..
Hope this helps

So, I've read the recommendations and I'd have to say: Can't really be done, definitely not reliably. If you try to use use any of the solutions and trust them, the only thing you can guarantee is that one day when you aren't expecting it, they will let you down.

(if you open a second separate window and wait for a response in the second that window but the user closes the second window then you have to open a third window to handle the second one closing prematurely etc etc)
