I got the answer from this web post:
http://stackoverflow.com/questions/1270347/unexpected-flash-security-exception-when-using-urlloader
Instead of setting the contentType like this:
request.contentType = "multipart/form-data;boundary=" +
POSTUploadBuilder.boundary;
Set the contentType like this:
request.requestHeaders.push(new URLRequestHeader('Content-Type',
'multipart/form-data; boundary=' + POSTUploadBuilder.boundary));
This is how I create the boundry in my POSTUploadBuilder class:
public class POSTUploadBuilder {
private static var _boundary:String = "";
private static var _mainBoundary:String = "";
public static function get boundary():String {
if(_boundary.length == 0) {
var i:uint = 0;
var len:uint = 0x20;
for(; i < len; ++i) {
_boundary += String.fromCharCode(uint(97 + Math.random() *
25));
}
}
return _boundary;
}
