## Class SessionContextRequestHandler

- java.lang.Object
- - org.apache.cayenne.configuration.web.SessionContextRequestHandler

- All Implemented Interfaces:
    RequestHandler

      public class SessionContextRequestHandler
      extends Object
      implements RequestHandler

  Default implementation of the `RequestHandler` that stores per-user `ObjectContext` in a web session and binds it to request thread. Note that using this handler would force `HttpSession` creation, that may not be desirable in many cases. Also session-bound context may result in a race condition with two user requests updating the same persistent objects in parallel.

  User applications in most cases should provide a custom RequestHandler that implements a smarter app-specific strategy for providing ObjectContext.

  For stateless (per request) context creation use `StatelessContextRequestHandler`.

  Since:
    3.1
