title: How to use a connection to database saved in a session in DataAbstract/RemObjects?
body: <p>In the DataAbstract sample application "Old\Connection By User" the procedure "AcquireHoldButtonClick" creates a connection to the database and stores a reference in the user's session variable.
  I plan to use such a mechanism but fail to understand where and when I will need to access this session variable to provide the correct connection for that user.</p>
  
  <p>As an example, when I call the ApplyUpdates method on the client, the server will have to access the connection in the session but I don't know which event I have to catch from the server to achieve that ?</p>
