Our application has been working for several years, but recently we got a lot of complaints from users that can no longer log in. Our app is set up to link a user to a workstation using a cookie (s)he receives on the first connection. Apparently, this cookie is nicely transferred to the workstation, and the user is requested to login again. At that point the request does not contain the cookie and the login is refused. Yet when looking in the cookie info, the cookie is present on the workstation. Has anyone any suggestions as to why this goes wrong?
