Multiple HTTP sessions - WDA Refresh

[Former Member]

Hello Experts,

We created a webdynpro abap that generates a report in link with IW29 transaction (ZPM_IW29_WDA) :

We have implemented an auto refresh with a time set in TVARVC. This time is retrieved at the initialization of webdynpro and saved in an attribute (TIMER). We have a second attribute to generate the URL to call. Here management attributes:

=> TIMER attribute is used to set the delay property on action REFRESH

Problem:

The auto refresh working properly but after some refresh we have several HTTP session that are created for the same user (Visible in SM04) :

We believe that this problem is due to the call of the URL for each refresh, a new session is created. We added these options in service to avoid new sessions:

• ~nosplash = 1
• ~disconnectOnClose = 1
• ~sessionLazyDisconnect = 1

But the problem still persists, can you help us on this anomaly please?

Thank you in advance.

Are you using HTTP security session management? Check in transaction SICF_SESSIONS. Also see in transaction SM05 whether the sessions have distinct session IDs. It might be a bug in the session handling, so I would suggest you to try with the latest kernel patch level. That said, it is inherit to HTTP(S) to open multiple connections but they should all share the same backend session as long as the session ID is passed to the backend.
