Question

I need to find out the subdomain from which a SOAP-based client calls a WCF-method. While that is quite easy if your’re on ASP.NET by using HttpContext.Current, I could not find an equivalent for WCF.

The reason why I need this value is, because I want to host a multi-tenant application which consists of a Web-Frontend (like “foo.myservice.com”) and also provides a SOAP-based API (like “foo.myservice.com/Services/ClientService.svc”).

Any idea?
Thany you!

Assuming that you are using HTTP based binding, you can either enable the ASP.NET compatibility to access HttpContext or use OperationContext to gather the data you want.

OperationContext.Current.RequestContext.RequestMessage.Headers.To should work in your case and return the Uri of the request.
