In my asp.net application, i want to clear the session whenever my browser closed or my tab (if my browser containing multiple tabs)closed.
Please guide me to get out of this issue…
Short version, No.
There’s no solid way of a server detecting if the client has closed their browser. It’s just the nature of web development’s asynchronous pattern.
Long version, if it’s really, really important to you;
Put a bit of javascript in the page that sends a regular post to your website in the background and set up a serverside agent or service that disposes of the sessions if it doesnt receive these regular “heartbeat” signals.
You can put a javascript postback onto the page’s unload() event but dont rely on it, it doesnt always fire.
