title: Can't I set a variable at property url mx:HTTPService?
body: <p>I build an application that need httpservice feature. This application will be deployed at some computer. So, I don't have an idea to set variable at url property.</p>
  
  <pre><code>  &lt;mx:HTTPService id="personRequest" url="http://118.97.239.36/dokeos/main/webservices/send_sip.php"
       useProxy="false" method="GET" resultFormat="text" result="personJSON(event)"&gt;
      &lt;mx:request xmlns=""&gt;
        &lt;getPerson&gt;"true"&lt;/getPerson&gt;
      &lt;/mx:request&gt;
    &lt;/mx:HTTPService&gt;
  </code></pre>
  
  <p>I already try with block {}, but no use.</p>
