Server.Processing.DuplicateSessionDetected

      Earlier i faced one issue with BlazeDS 3.2.0

Issue :

Fault Code : Server.Processing.DuplicateSessionDetected.

Error Message : Detected duplicate HTTP-based FlexSessions, generally due to the remote host disabling session cookies. Session cookies must be enabled to manage the client connection correctly.

Reproducing steps :

1. Open your application in two different tabs (basically these two tabs will share same session) and then close one tab.

2. Do any action (related to server interaction ) in other tab..then u can see the exception.

Solution :

Actually you find so many solutions for this problem just like writing custom adaptor etc.

But, my suggession if you are not really concern with BlazeDS version, roll back to BlazeDS 3.0.0.544.
