Javascript proxy URL generated by .SVC file does not work under SSL

I have an ASP.Net web site deployed in IIS 7.5 with a file Cart.svc (used for Javascript access from the browser).

The javascript renders fine under non SSL but SSL causes it to halt. However, if you take the /js suffix off, it works, even under SSL. So it looks like there IS a process listening on SSL, it just does not like the /js suffix.

The server side error is;

WebHost failed to process a request.

Update 2: Working config below

  <system.serviceModel>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />

        <endpoint address="" behaviorConfiguration="MySite.Website.CartAspNetAjaxBehavior" binding="webHttpBinding" bindingConfiguration="webHttpBinding" contract="MySite.Website.Cart" />

          <enableWebScript />
        </behavior>
      </endpointBehaviors>

Have you set your binding's settings to use Transport level security?

<binding name="xxx">
    <security mode="Transport"></security>
</binding>

If you can post your section, that would help.
