Hi,

When you open a new browser window from an existing window (either by target="_blank", javascript window.open(), or Crtl-N), the new window will share all the non-persistent cookies with the existing window. If you open a new instance of the browser by double clicking the browsers icon or going through the start menu, the new browser window contains it's own non-persistent cookies.

Is there any way to open a new instance of a browser window from an existing browser window (using ASP or JavaScript) so that these non-persistent cookies are not shared between the two windows?

Thanks

Nope. Using a non existent target, or window.open(), or ctrl-N will always open the new window in the same session.
