Hello,

Found lots of articles talking about why URLLoader.bytesTotal is zero because theres no HTTP header content-length. Adding this in PHP fixed the problem when run in Flash, but when uploaded to server, it returns zero again. Does anyone know why? It cant be a server issue because it works when tested in Flash, and I’ve checked for the HTTP content-length header, it is there.

Thanks
