Closing of DWA

Whenever we logout from DWA, the screen will show a “Close Window” page. Is there a way to set a timeout so that the page will close by itself?

Due to access ristrictions, a webpage is not able to close it’s own window.

I saw someone doing it but I’m not able to get the info as how it was done.
