Login to any application, which has a login page. (say "http://mail.yahoo.com"). Keep the session active, i.e., DO NOT log out.

Run the following script.
require 'WET'
include WET
ie = Browser.new()
ie.goto "http://mail.yahoo.com"

The second IE session that opens up, directly goes inside, skipping the login page.

Right now, the only way to again make the ie.goto "<URL>" to go through the login page, is by running the script with no IE sessions Open.

The present defect also prevents running of two sessions of the same URL. {Especially this is needed when we need to have two sessions open with different logins}


Note:
      (a) As far as I remember, till a month back, this was working FINE. Hence the bug can be classified as a regression bug.
      (b) This issue is NOT reproducible manually. i.e., even if one session is active, if the second session is launched with the same URL, the login page is shown.
