A method and apparatus for authenticating a client to a content server. A
ticket authority generates a ticket associated with the client. The
ticket comprises a first ticket and a second ticket. The ticket authority
transmits the first ticket to the client and the client uses the first
ticket to establish a communication session with an content server proxy.
The ticket authority then transmits a second ticket to the content server
proxy and the content server proxy uses the second ticket to establish a
communication session with the content server.
