HOWTO: avoid orphaned REST invocations due to lost responses

Your REST service is invoked and left pending. How can you rollback?

So you have a REST service and it is being called - good, your project is a success

Now suppose you want to rollback invocations where the response is lost, so the caller never knew your service actually did something. This is an "orphaned" invocation of your service, leaving you with some garbage transaction data that you don't want. How can you deal with this?

We offer two solutions:

• The classical, ACID way, or
• Our newer vision for REST

Either of these will make sure that orphaned invocations are cleaned up after some timeout.

Enjoy!
