Resumable Downloads with AIR

Here is how a sample Request looks like:

GET /files/richflv/help/ExportOptions.flv HTTP/1.1
Referer: app-resource:/LoadingTest.swf
x-flash-version: 9,0,60,153
Range: bytes=1200000-1300000
User-Agent: Mozilla/5.0 (Windows; U; en) AppleWebKit/420+ (KHTML, like Gecko) AdobeAIR/1.0
Host: www.richapps.de

In Actionscript we can write a custom header like this:

var header1:URLRequestHeader = new URLRequestHeader("range","bytes="+currentBytesPosition+"-"+toRange);
var re:URLRequest = new URLRequest(downLoadURL);
re.requestHeaders.push(header1);
currentBytesPosition = toRange;
urlStream.load(re);
