Abstract
An authentication mechanism is provided for a web method platform that allows homogeneous access for different types of clients according to a bootstrapping procedure utilized to establish the session. Different clients can be assigned different levels of trust based in part on the bootstrapping procedure and/or information provided during the procedure. The bootstrapping procedure can produce a token that is used by the clients in subsequent requests to provide previous authentication or state information to the platform. The token can comprise a shared secret used to ensure integrity of communications in some cases, and the token can be opaque to the client. Tokens can expire and require a client to re-bootstrap to provide higher levels of authentication protection, and tokens can be shared among a plurality of application servers to facilitate effective handling of requests in a farmed environment.
