Re: [flexcoders] Re: Sending a HEAD request

[Weyert de Boer]

Today on Twitter I heard about this library as3httpclient. Appears to  
support doing HEAD requests. See: http://code.google.com/p/as3httpclient/

You could probably use the URLLoader class 
(http://livedocs.adobe.com/flex/3/langref/flash/net/URLLoader.html) but then 
you would have to worry about the security sandbox.

I have not done it but it looks doable.

Thank you,

Is there a way to do the same thing directly in actionscript?

You could include a javascript function in the wrapper and call it from 
externalInterface.call. Something like...

function UrlExists(url)
{
  var http = new XMLHttpRequest();
  http.open('HEAD', url, false);
  http.send();
  return http.status!=404;
}
