The application dispatches HTTPStatusEvent objects when a network request returns an HTTP status code.
HTTPStatusEvent objects are always sent before error or completion events. An HTTPStatusEvent object does not necessarily indicate an error condition; it simply reflects the HTTP status code(if any) that is provided by the networking stack. Some Flash Player environments may be unable to detect HTTP status codes; a status code of 0 is always reported in these cases.
In Flash Player, there is only one type of HTTPStatus event:
httpStatus. In the AIR runtime, a FileReference, URLLoader, or
URLStream can register to listen for an

The response headers that the response returned, as an array of URLRequestHeader objects.
The URL that the response was returned from. In the case of redirects, this will be different from the request URL.
The HTTP status code returned by the server. For example, a value of 404 indicates that the server has not found a match for the requested URI. HTTP status codes can be found in sections 10.4 and 10.5 of the HTTP specification at [http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html](http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html).
If Flash Player or AIR cannot get a status code from the server, or if it cannot communicate with the server, the default value of 0 is passed to your code. A value of 0 can be generated in any player(for example, if a malformed URL is requested), and a value of 0 is always generated by the Flash Player plug-in when it is run in the following browsers, which do not pass HTTP status codes to the player: Netscape, Mozilla, Safari, Opera, and Internet Explorer for the Macintosh.
