org.dmd.dmp.server.servlet.extended.SessionRI
The SessionRI class represents an authenticated user session. All requests are verified by the security manager to ensure that they have a valid session. Sessions also create the named event channel for the GWT Event Service through which we send DMPEvents and asynchronous responses.
The SessionRI is at the heart of all interactions between the client and the server. Each session has a unique registration with the cache so that all operations performed against the data can be uniquely identified as coming from a particular cache registrant. This allows us to distinguish who did what to the data. On the client, this mechanism can be used to determine whether events coming from the server were caused by you or by some other client.
