title: How do I call a webservice without a web reference?
body: <p>I want to call a web service, but I won't know the url till runtime.</p>
  
  <p>Whats the best way to get the web reference in, without actually committing to a url.</p>
  
  <p>What about having 1 client hit the same web service on say 10 different domains?</p>
