ActionScript 3.0 :: Download A 1kb Text File On Startup To Check If There Is A Connection?

I need to attempt to download a 1kb text file on startup to check if there is a connection. This is because of the environment.

I realised:

PHP Code:

//...testLoader.addEventListener(IOErrorEvent.IO_ERROR,someErrorHandler) 

or:

PHP Code:

try {        //...         testLoader.load(someURLRequest);}catch (e:Error){          someErrorHandler();           }
