title: Making signalr generated proxy hubs url dynamic
body: <p>I have a solution which need to connect using CORS to a signalr exposed service.
  The address where the signalr service will be hosted could change in time, so it's not 
  suitable to have the classic script tag </p>
  
  <pre><code>&lt;script src="http://server:8888/signalr/hubs" type="text/javascript"&gt;&lt;/script&gt; 
  </code></pre>
  
  <p>but it would be fantastic if there's a way to reference the above url dynamically by javascript without the static script tag.
  Suggestions would be great!</p>
