title: Accessing the full url, including hostname with jstl
body: <pre><code>&lt;c:url var="myUrl" value="/MyPath/${MyID}"/&gt;
  </code></pre>
  
  <p>which I then use later (to enable users to copy links) : </p>
  
  <pre><code>&lt;input size="35" disabled value="${myUrl}" /&gt;
  </code></pre>
  
  <p>and it shows</p>
  
  <pre><code>/my-app-name/MyPath/23
  </code></pre>
  
  <p>however I want it to be </p>
  
  <pre><code>http://myHost/my-app-name/MyPath/23
  </code></pre>
  
  <p>I can prepend the string sure, but wanted a way to actively get the correct hostname ... ?</p>
