HTTP Status error 0

Hello all,

I am writing a flash app which requires words to be checked against a dictionary stored on a server, and am doing the following call to a servlet from within an swf file.

var url:String = “http://<myDomain>/wordcheck?words=test”

_loader = new URLLoader();
_loader.dataFormat = URLLoaderDataFormat.TEXT;
var request:URLRequest = new URLRequest(url);
_loader.load(request);

The swf file is sitting on the same domain as the server and I set Local Playback Security to ‘access network’.

It all works fine in Internet Explorer but on other browsers I just get HTTP Status 0.

Any ideas what I’m doing wrong?
