Hi Andrus,
Let me see if I understand the Hessian sessions correctly.
It seems to me that every unique DataContext in 3T opens a new
HessianConnection, thus establishing a new Hessian session. However, this
Hessian session is not tied to (and it doesn't appear possible to tie it to)
the physical HttpSession.
Our client/server application requires us to write user authentication on the
server. However, the user data is stored in the database. Additionally, once
the user is verified, all peer contexts on the server, have to be "tied" to
that user. We're hoping to (eventually) implement quite sophisticated
connection control on the server.
Ideally, the point at which we intercept session information allows us to
access both connection data (IP address, SSL certificates, etc) and Cayenne
data (DataContext, Hessian session, etc).
It appears that hacking into HessianServlet allows us to obtain connection
data, hacking into HessianService allows us to get Cayenne data, however
there is nothing that allows us to connect the two types of data together...
any hints :)
