Identifying WCF Client ID

Question

I have a WCF web service that exposes several business methods. I also have two clients - an asp.net GUI and a data migration application that both connect to the wcf backen

You can solve this via a custom header.

You can add a custom header as part of the endpoint in the client application's configuration file. You would then make each client's custom header different. For example, in the ASP.NET version:

        
            
                ASP_Client
            
        

Then the service can check the header value like so:

public void MyServiceMethod()
{
   var opContext = OperationContext.Current;
   var requestContext = opContext.RequestContext;
   var headers = requestContext.RequestMessage.Headers;
   int headerIndex = headers.FindHeader("ClientIdentification", "");
   var clientString = headers.GetHeader(headerIndex);
   if clientString=="ASP_Client"
   {
       // ...
   }
   else
   {
      // ...
   }
}
