19.2 Session Management in the Servlet Execution Engine

Each session object in the servlet execution engine is an instance of rwsf::HttpSession containing a collection of attributes, or instances of rwsf::Attribute.

For client requests, this session object is passed in the HTTP transport. When the request comes into the servlet, the session data is then placed into a rwsf::CallInfo object. rwsf::CallInfo holds SOAP and transport headers, as well as session information for a message.

The rwsf::CallInfo object gets passed through the message handler chain, ending at the server implementation.

For more information on session management and recovering state, see Section 7.5, "Recovering Session State," in the HydraExpress Servlet Development Guide.
