Answer 1

What I did to solve a similar problem was to force the webservice to emit the correct headers.

You can do the following:

1. Create the following class in the App_Code folder:

   using System;
   using System.Web.Services.Description;
   
   namespace Msdn.Web.Services.Samples
   {
     /// <summary> Summary description for WSDLReflector </summary>
     public class WSDLReflector : SoapExtensionReflector
     {
       public override void ReflectMethod()
       {
         //no-op
       }
   
       public override void ReflectDescription()
       {
         ServiceDescription description = ReflectionContext.ServiceDescription;
         foreach (Service service in description.Services)
         {
           foreach (Port port in service.Ports)
           {
             foreach (ServiceDescriptionFormatExtension extension in port.Extensions)
             {
               SoapAddressBinding binding = extension as SoapAddressBinding;
               if (null != binding)
               {
                 binding.Location = binding.Location.Replace("http://mywebservice.comp.com", "https://uat.mywebservice.com");
               }
             }
           }
         }
       }
     }
   }
   

2. And add this to web.config:

   <webServices>
     <diagnostics suppressReturningExceptions="true" />
     <soapExtensionReflectorTypes>
       <add type="Msdn.Web.Services.Samples.WSDLReflector,App_Code"/>
     </soapExtensionReflectorTypes>
   </webServices>
