An improved session control method and apparatus includes a client which establishes a session with a first server such that the first server can identify the client. When the client wishes to migrate from the first server to a second server, the client requests a session token from the first server. The session token is a data element generated by the first server which is unique over the client-server network being navigated and identifies the particular session with the first server. The session token is preferably a difficult to forge data element, such as a data element digitally signed using the private key of the first server. The session token is passed from the client to the second server to initiate migration to the second server. If session data is too bulky to be passed as part of the session token, the second server may use data from the session token to formulate a request to the first server for additional data needed to handle the state of the session. To minimize the transmission of data, the second server might maintain a version of the bulk session data and only request an update to the version of the data indicated in the session token.
