title: url encoding using Flex navigatetoUrl function
body: <p>I want to post data to a URL on my server from a Flex app. im using the following </p>
  
  <pre><code>UrlParam = UrlParam + '&amp;name='+ name.text + '&amp;business=' + buisness.text;
  navigateToURL(new URLRequest(UrlParams),'_self');
  </code></pre>
  
  <p>the problem im having however is that if i enter a business with an ampersand ("A&amp;b.com") then the name does not send.</p>
  
  <p>Does Flex have anything out of the box to do the encoding from <code>&amp;</code> to <code>%26</code>?</p>
