Fat Cookie

The Fat Cookie is being deprecated and will be replaced by UTLogin. The Fat Cookie is scheduled to be retired in June 2014. For Web Central publishers, ITS has created the Transitional Fat Cookie that will allow Web Central-hosted sites to continue to operate as expected after the Fat Cookie system is retired and until Web Central itself is retired.

The 'Fat Cookie' refers to a deprecated, modified version of a normal browser cookie that was encoded and digitally signed. The fat cookie contained biographical information about the user. It allowed services not deployed on specific administrative machines to use UT EID logon authentication.

The fat cookie allowed access the following fields:

  • Name

  • UT EID

  • UIN

  • Assurance level

  • Cookie expiration time

  • Number of roles

  • Roles (In the format Component-Role-Status)

  • IP address

  • Cookie status

  • Keyid

  • Version
