title: RestAPI, using '/' in params
body: <p>If I have</p>
  
  <pre><code>GET /api/product/:path
  </code></pre>
  
  <p>And do a request:</p>
  
  <pre><code>GET /api/product/http://otherapi/params/format=json
  </code></pre>
  
  <p>This will not work. How do I encode my path so it will work?</p>
