This week's book giveaway is in the Performance forum. We're giving away four copies of The Java Performance Companion and have Charlie Hunt, Monica Beckwith, Poonam Parhar, & Bengt Rutisson on-line! See this thread for details.
I have made a server program using java socket, in which user hits my url and in response I am sending continous
stream of data which is changing at user browser.
if user closes the browser or open a new tab then that stream of data should be stopped.
My concern is ,how to detect any event if user close their browser or change the tab.
