Abstract
A method and apparatus for using a session identifier to identify a specific data communications session between an apparatus and an external apparatus is disclosed. When a data communications session is initiated between the apparatus and an external apparatus, the external apparatus sends authenticating information to the apparatus. The apparatus uses the authenticating information to determine the identity and the privileges of the external apparatus for the particular session. A unique session identifier is created by the apparatus, and the session identifier is associated with the external apparatus's identity and privileges. The session identifier is passed between the apparatus and the external apparatus with each subsequent data communication in the session until the session is terminated. The apparatus uses the session identifier received with the data communications to identify the external apparatus and its privileges and allocate resources accordingly. The session identifier is encoded using a six bit code, thereby making it compatible with the Internet e-mail protocol and while also optimizing data compression. The encoded session identifier may be transmitted by appending it to a URL like a query string.
