WCF: Programmatically enable both https and http on same ip/port

Question

I have read some posts here, claiming that WCF can allow http and https on the same endpoint/port, but that sounds a bit wrong to me. I tried to set it up but I cannot figure out how to enable both https and http listening on the same port/ip, programmtically .

I get the following error when I try to add https:

'System.ServiceModel.AddressAlreadyInUseException' in System.ServiceModel.dll HTTP could not register URL https://+:10901/Service/ . Another application has already registered this URL with HTTP.SYS.

It works fine if I add just one of them.

Code:

Uri httpsUri = new Uri("https://" + localIp.ToString() + ":" + settings._WebservicePort.ToString() + "/Service/");
Uri httpUri = new Uri("http://" + localIp.ToString() + ":" + settings._WebservicePort.ToString() + "/Service/");

host = new WebServiceHost(typeof(Service), httpUri, httpsUri);

WebHttpBinding whbHttp = new WebHttpBinding
{
    CrossDomainScriptAccessEnabled = true,
    Security = { Mode = WebHttpSecurityMode.None },
    MaxReceivedMessageSize = 10000000
};

WebHttpBinding whbHttps = new WebHttpBinding
{
    CrossDomainScriptAccessEnabled = true,
    Security = { Mode = WebHttpSecurityMode.Transport },
    MaxReceivedMessageSize = 10000000
};
ServiceEndpoint seHttp = host.AddServiceEndpoint(typeof(IService), whbHttp, httpUri);
seHttp.Behaviors.Add(new WebHttpBehavior());

ServiceEndpoint seHttps = host.AddServiceEndpoint(typeof(IService), whbHttps, httpsUri);
seHttps.Behaviors.Add(new WebHttpBehavior());

ServiceDebugBehavior stp = host.Description.Behaviors.Find<ServiceDebugBehavior>();
stp.HttpHelpPageEnabled = true;

host.Open(); // <-- Exception: 'System.ServiceModel.AddressAlreadyInUseException' in System.ServiceModel.dll HTTP could not register URL https://+:10901/Service/. Another application has already registered this URL with HTTP.SYS.

I realize that web http is port 80 and https is normally 443, but why am I then reading that http and https can be hosted on the same port? Am i misreading, and its actually not possible? =)

I'm not sure this is what you want. but i just go ahead and post my answer. hosting http and https both on single port is impossible. but you can have both http and https binding like this:

<bindings>
      <webHttpBinding>
        <binding name="RestBinding"/>
        <binding name="SecureRestBinding" >
          <security mode="Transport"/>
        </binding>
      </webHttpBinding>
    </bindings>
    <services>
      <service behaviorConfiguration="ServiceBehavior" name="YOURPROJECT.YOURSERVICE">
        <endpoint address="" behaviorConfiguration="Web" binding="webHttpBinding" bindingConfiguration="RestBinding" name="Rest" contract="YOURPROJECT.IYOURSERVICE"/>
        <endpoint address="" behaviorConfiguration="Web" binding="webHttpBinding" bindingConfiguration="SecureRestBinding" name="SecureRest" contract="YOURPROJECT.IYOURSERVICE"/>
      </service>
    </services>
