title: How to demo a REST API without a REST client
body: <p>I need to build a way to demo a REST API that takes three or four inputs, makes a REST call to an external server, then displays the response. This demo needs to be performed by a rather limited technical audience to business so REST clients are out. </p>
  
  <p>It seemed like a simple HTML page that would do an ajax call would be fine for this, except I ran into the <code>No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access</code> fun messages because my localhost domain does not match the target domain. I don't have access to the target REST web service, so I can't make the necessary changes for the <a href="http://www.html5rocks.com/en/tutorials/cors/" rel="nofollow" title="CORS">CORS</a> headers. </p>
  
  <p>Any ideas?</p>
