Hello

I went through few modules of SER regarding the session maintenance. When i walked through the Transaction Module, I came to know that SER provides Stateful Proxy. I have few questions regarding this:

1. How does SER maintains session? i.e., Does it maintain any state table similar to file/socket descriptor?

2. In the case of "dialog" interaction between clients are identified by callID and routed through the Record-Route. Does Record-Route traces the session? If so where it is maintained? Will this become a overhead in header while routing all the details? Does the client feel efficient in performance?

3. How does SER knows whether the session is disconnected or logged off? And under what situation does the SER stores the offline messages?

4. Can you provide me the total architecture of how the stateful proxy is designed and works?

Can you please update me for the above mentioned questions.

Thanks Dharani.
