Multiple browser tabs sharing session by default

Published on Monday, November 8, 2010

Normally browser such as IE, Firefox, if you open multiple tabs, all tabs share session cookies with the 1st opened tab.

I think this is simple to test, I think most of people know that .

However, if you want to see the official document about sharing session: please check here (from Microsoft IE blog)

In contrast, if you click New Window, New Tab, or Duplicate Tab on the File menu, or click on a desktop shortcut, the new tab or window will share session cookies with the original tab. This is called "session merging."
