We have a WCF service that is being hosted on a set of 12 machines. There is a load balancer that is a gateway to these machines.

Now the site is setup as SSL; as in a user accesses it through using an URL with https. I know this much, the URL that addresses the site is https, but none of the servers has a https binding or is setup to require SSL. This leads me to believe that the load balancer handles the https and the connection from the balancer to the servers are unencrypted (this takes place behind the firewall so no biggie there).

The problem we're having is that when a Silverlight client tries to access a WCF service it is getting a "Not Found" error. I've set up a test site along with our developer machines and have made sure that the bindings and endpoints in the web.config work with the client. It seems to be the case in the production environment that we get this error.

Is there anything wrong with the following web.config? Should we be setting up how https is handled in a different manner?

We're at a loss on this currently since I've tried every programmatic solution with endpoints and bindings. None of the solutions I have found deal with a load balancer in the manner we're dealing.

(The addresses are of no consequence since those are dynamically built so that they will point to a dev's machine or to the production server)
