WCF over IIS through load balancer reports wrong base address - wcf

Question

I'm trying to launch a WCF service over SSL on IIS 6 through a load balancer. My initial problem was an obvious and pretty well discussed one - the address shown on the WSDL page pointed to https://SERVERNAME/WebServices/mydomainws.svc instead of www.mydomain.com. The answer to this problem is to add a host header value in IIS. I did that and it worked... sort of. I now get http://www.mydomain.com/WebServices/mydomainws.svc when viewing the wsdl in a browser. If I click on that link (the non-ssl link) I get a service definition that again references the server name.
The next oft recommended remedy is to use WCF Extras which provides an extension that allows you to specify a base address. But setting that config entry only updated the soap12:address. The EndPointReference address is still using the machine name.
To summarize: WSDL as viewed in web browser at https://www.mydomain.com/WebServices/mydomainws.svc: http://www.mydomain.com/WebServices/mydomainws.scv
Clicking the above link brings me to an actual wsdl file with the following service entry:
https://ServerName/WebServices/mydomainws.svc
My server config file has the following serviceModel entries:
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="TransportSecurity">
<security mode="Transport">
<message clientCredentialType="None"/>
<transport clientCredentialType="None"/>
</security>
</binding>
</wsHttpBinding>
</bindings>
<services>
<service name="mydomain.ws.mydomainws" behaviorConfiguration="mydomainwsBehavior">
<!-- Service Endpoints -->
<endpoint address="" **behaviorConfiguration="CorrectEndPoint"** binding="wsHttpBinding" bindingConfiguration="TransportSecurity" contract="mydomain.ws.Imydomainws"/>
<endpoint address="mex" **behaviorConfiguration="CorrectEndPoint"** binding="mexHttpsBinding" contract="IMetadataExchange"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="mydomainwsBehavior">
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="true" />
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
<endpointBehaviors>
**<behavior name="CorrectEndPoint">
<wsdlExtensions location="https://www.mydomain.com/WebServices/mydomainws.svc" singleFile="true"/>
</behavior>**
</endpointBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
<extensions>
<behaviorExtensions>
<add name="wsdlExtensions" type="WCFExtras.Wsdl.WsdlExtensionsConfig, WCFExtras, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
</behaviorExtensions>
</extensions>
</system.serviceModel>
Can anyone point me in the right direction?
Thanks,

This should be handeled by new behavior useRequestHeadersForMetadataAddress. Try to add this to your service behavior:
<serviceBehaviors>
<behavior name="LoadBalancedBehavior">
<serviceMetadata httpGetEnabled="true" />
<useRequestHeadersForMetadataAddress>
<defaultPorts>
<add scheme="http" port="80" />
<add scheme="https" port="443" />
</defaultPorts>
</useRequestHeadersForMetadataAddress>
<!-- Other service behaviors as necesary -->
</behavior>
</serviceBehaviors>
This behavior is availabel in WCF 4.0 and should be available as KB for WCF 3.x.
