How to build conditional flows that return status code 405 (method not allowed) if the verb & path combination is not allowed.
Add a ConditionalFlow**(invalid-verb-path-flow)** just before the PostFlow in ProxyEndpoint. Use a RaiseFault policy with no Condition.
So whenever the proxy receives a verb/path combo which did not match the Earlier Conditions, it would come to the invalid-verb-path-flow and execute the RaiseFault.
Within RaiseFault use our 405 code and custom error message.
