Closing Multiple Tab in Broswer ASP.Net/C#.Net

Hi!

Is there a way to close the prior opened tabs in a browser once you're open a new tab?
 
For example, you have log in in a website, then you've open some link using Ctrl+click (click the link), it will open in another tab. However, once you open a new tab and type the login page again, i need to close the other tabs and leave only the LOG IN page.
