Auto-Login Credential Cookie
The auto-login credential cookie underlies the Remember My User ID and Password feature on the login page. This cookie consists of the username and password for a given user, and the URL string used to access the application. The auto-login credential cookie is persistent and is stored on the user's browser in encrypted form (it is always encrypted). The RC4 algorithm encrypts this cookie. The result of this encryption is then encoded using base64 Content-Transfer-Encoding. This cookie applies to the Siebel Web Client only.
The auto-login credential cookie is not mandatory. It is an optional way to allow users not to have to enter their username and password every time they log in. If the user subsequently accesses the application URL through another browser window, the user information is provided to the application so the user does not have to log in again.
The format of the auto-login credential cookie is as follows:
NOTE: Functionality provided by the auto-login credential cookie is not available in cookieless mode.
