Steps to reproduce

IE11 Version: 11.0.9600.18314
Update Versions: 11.0.31 (KB3154070)
OS: Windows 7 Pro

Browser intermittently drops the cookies and causing the user redirected to login page with our vendor site. The Fiddler shows cookie getting dropped and server is returning 302 with login page. This is not easy to create and vendors have trouble to reproduce in their environment.
I thought if we can use the proposed workaround by setting registry as specified in the below link it would solve our problem. But that option is also ruled out. We are also not using persistent cookies and Fiddler shows one IE process ID.

    • Thank
      you for the feedback. This issue appears to have been fixed in Microsoft Edge.
      We’re not presently working on feature bugs in Internet Explorer outside of
      security-related issues. If you have a premier support contract you can visit and open
      a support incident and work with an engineer to address this issue.

    • Brad,
      This problem did not occur in IE11 prior to the 1607 release. The Edge browser did have the problem prior to 1607 and it was fixed in 1607.

      However, IE11 became broken with the 1607 update.

      Best Regards,

    • HI Don: Whats is the FIX for this issue? I’m facing similar issue with
      Windows 10 and IE11 (OS Build 10586.1045)

      Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; rv:11.0) like Gecko.


    • We are also having the same issue with our web application. Multiple simultaneous requests in different tabs are making the browser to drop the cookie and trying to open a new session. Solutions mentioned in the link in the main post have not helped to solve the issue. We are using the following version of IE.

      Version: 11.0.9600.18792
      Update versions: 11.0.46 (KB4036586)

    • I am also facing same issue. When trying to open new window from IFRAME control. But my issue was resolved when I added below registry entry on my local machine :

      HKEY_CURRENT_USER/Software/Microsoft/Internet Explorer/Main/TabProcGrowth and set value to 0

      Hopy this will solve the problem !
