ESB Relay with webHttpRelayBinding binding IIS hosting

Hello,

I try to expose legacy LOB WCF service using webHttpBinding binding to the internet by refactoring it to use webHttpRelayBinding binding so it can be accessed through Azure ESB relay endpoint.

The service operates as expected when self-hosted in console app but we are not successful so far using IIS as the hosting environment.

We suspect that the issue we are facing is related to proper configuration of SSL support on our IIS server.

I had no lack so far in finding any detailed info related to set up of relays in Azure and what is required to properly configure IIS to host HTTP based requests coming through the relay endpoint.

Any help/input is appreciated

Regards

Jack

Here is response I am currently getting

<Reason>

<Text xml:lang="en-US">The message with Action 'GET' cannot be processed at the receiver,

due to a ContractFilter mismatch at the EndpointDispatcher.

This may be because of either a contract mismatch (mismatched Actions between sender and receiver)

or a binding/security mismatch between the sender and the receiver.

Check that sender and receiver have the same contract and the same binding (including security requirements,

e.g. Message, Transport, None).
