How to start a session from an existing session?

[Larry Lau]

Hi,

I would like to know if it is possible to launch a new browser instance from
an existing browser instance with a separated newly created session.
window.open(url) already keep you in the same session as expected.

Problem I am trying to solve...

1. A url pointing to a document is sent to a user in email. (document can
only be accessed by this user)
2. User will click on the link in outlook to access the document
2a. If user already logged on to the application in an existing browser
instance, outlook will use it.
2b. If there is no browser instance, outlook will launch a new IE
instance and user will prompt to login.

In Step 2b, if the user used a different user id to log on to the
application in the existing browser instance, the application will fail
because the current logon user has no permission to the document.

Note: one user can have multiple user id to the application.

I can solve the problem if I can launch a new browser with new session and
redirect the user to the login page while leaving the existing browser
alone.

I didn't want to do System.Web.Security.FormsAuthentication.SignOut() on the
existing browser because the user may be doing something important.

Thanks!
