[flexcoders] Re: Sending a HEAD request

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;
}

 Hi,
 
 The server side dev team have asked if I can send a HEAD request to their 
 home page in order to 'keep my flex app logged in'
 
 What is the best way of going about this.
 URLRequest will not allow the method as  a HEAD as far as I can see.
 
 And URLLoader returns the html data, I basically need to send only
 
 Any ideas much appreciated
 
 thanks Steve

Thank you,

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


thanks Steve

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.

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