Hi,
Just curious, did anybody use WS-AT protocol to propagate transactions in WCF over the Internet in production(wsHttpBinding)? Is it hard to deploy/support? Is it a good approach to keep a WS-AT port open? Or maybe it is better to have a custom solution to support transactions? What do u think?
We have not used it.
Main reason is that we do not think that it is a good idea.
The problem is that you are then allowing a client on the internet to take a lock on your system. What happens if the client looses connection? You then have locks on your system that must wait for a timeout.
You reduce the scalability of the system and leave it open to denial of service attacks.
