session expiration

if I am logged in on my application but 开发者_如何学JAVAif i choose closing browser without clicking on logout how will be I logged out from server automatically?

Unless you have the user explicity log out, your server cannot know the user has closed their browser.

You can simply let sessions timeout naturally, for example, after ten minutes of inactivity.

Alternatively, you can add some js to the page to make regular pings back to the server to keep a session alive while the browser window is open.
