[SIPForum-discussion] What is request/response stateless/stateful

[Sam Cao]

Yes, if an UAS has a state machine to maintain every dialogs, and send
out/process valid request/response upon current state, it is stateful;
otherwise, if server just transparently forward any response/request message
to another endpoint, and don't care it is valid or invalid, it is stateless.


Please refer to section 8.2.7 of RFC 3261 for more details. Wish this is
clear for you, Khoa.

Hello Pham,
Anything request/response,stateless is not remembering current transaction
and blindly forwarding it to other endpt.If server remembers/saves
transactions for its purpose  from one endpt and then forwarding it to
another endpt is stateful.

words itself gives u things clear-
state(transaction or session can be anything) ..so add now stateless-not
maintaing/remember the transaction and stateful-remembering the
transaction.
Hope am clear.
