As with Disconnecting, use this to clean-up any static resources or allocation tables related to a user session. DisconnectionEx adds additional information about the disconnect to assist in managing any additional resources associated with the session.
Contents of the sessionInfo Dictionary includes:
Key |
Value |
SessionKey |
The special identifier of this unique session |
SessionOwner |
The SessionOwner--similar to the http context User.Identity.Name but for situations where this may not be available. If no user identity has been configured, this will be the IP address of the client that connected to this session. |
SessionID |
Simple string portion of the SessionKey that is just the integer of the session starting at "1" |
ConnectedSeconds |
Number of seconds that the session was connected. |
UserLocation |
User's IP address |

The above sample demonstrates logging each user session disconnect.
