Running WCF is behind a loadbalancer, where the LB connection to IIS is http and the client connection to LB is HTTPS

Question

The setup looks something like this:

service client --httpS -> loadbalancer --http -> IIS containing WCF

I get this error:

A message with "https://MyDomain.com/Service.svc" cannot be processed at the receiver due to an AddressFilter mismatch in the EndpointDispatcher. Check if the end addresses of the sender and receiver agree.

I suspect this is because the service is configured to only run http. There is no certificate on the server because it is processed by the loadbalancer.

I know this: http://support.microsoft.com/kb/971842 (FIX: URIs in a WSDL WCF document refer to inaccessible internal instances)

We are working .Net 4.

I can provide more information, just not sure what would be useful at the moment.

thanks

If you have user password authentication, then WCF basichttpbinding will not allow this to get around this, clearusernamebinding , which would solve your problem.

If you do not have authentication, then for the above scenario, a generic basichttpbinding will suffice. Just configure your WCF service using basichttpbinding and just make sure that LB sends the request to the web server as http.
