title: NSURL parameterString with .NET service call
body: <p>I'm tring to use the NSURL class's parameterString message to return the string from the following url:</p>
  
  <pre><code>http://www.host.com/Api/Service.svc/GetStuff?param=thisIsTheParamValue
  </code></pre>
  
  <p>I keep getting <code>nil</code> for the parameterString. Does that url not conform to the standards that Apple uses?</p>
