Inheritance | HTTPStatusEvent Event Object |
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 Flash Player 9 |
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 httpResponseStatus
, which includes responseURL
and responseHeaders
properties. These properties are undefined in a httpStatus
event.

responseHeaders | property |
responseHeaders:Array
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 |
The response headers that the response returned, as an array of URLRequestHeader objects.
Implementation
public function get responseHeaders():Array
public function set responseHeaders(value:Array):void
See also
responseURL | property |
responseURL:String
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 |
The URL that the response was returned from. In the case of redirects, this will be different from the request URL.
Implementation
public function get responseURL():String
public function set responseURL(value:String):void
status | property |
status:int
[read-only] Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 Flash Player 9 |
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 ftp://ftp.isi.edu/in-notes/rfc2616.txt.
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.
Implementation
public function get status():int
HTTPStatusEvent | () | Constructor |
public function HTTPStatusEvent(type:String, bubbles:Boolean = false, cancelable:Boolean = false, status:int = 0)
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 Flash Player 9 |
Creates an Event object that contains specific information about HTTP status events. Event objects are passed as parameters to event listeners.
Parameterstype:String — The type of the event. Event listeners can access this information through the inherited type property. There is only one type of HTTPStatus event: HTTPStatusEvent.HTTP_STATUS .
| |
bubbles:Boolean (default = false ) — Determines whether the Event object participates in the bubbling stage of the event flow. Event listeners can access this information through the inherited bubbles property.
| |
cancelable:Boolean (default = false ) — Determines whether the Event object can be canceled. Event listeners can access this information through the inherited cancelable property.
| |
status:int (default = 0 ) — Numeric status. Event listeners can access this information through the status property.

HTTP_RESPONSE_STATUS | Constant |
public static const HTTP_RESPONSE_STATUS:String = "httpResponseStatus"
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 |
Unlike the httpStatus
event, the httpResponseStatus
event is
delivered before any response data. Also, the httpResponseStatus
event includes
values for the responseHeaders
and responseURL
properties (which are
undefined for an httpStatus
event. Note that the httpResponseStatus
event
(if any) will be sent before (and in addition to) any complete
or error
event.
The HTTPStatusEvent.HTTP_RESPONSE_STATUS
constant defines the value of the
type
property of a httpResponseStatus
event object.
This event has the following properties:
Property | Value |
---|---|
bubbles | false |
cancelable | false ; there is no default behavior to cancel. |
currentTarget | The object that is actively processing the Event object with an event listener. |
responseURL | The URL from which the response was returned. |
responseHeaders | The response headers that the response returned, as an array of URLRequestHeader objects. |
status | The HTTP status code returned by the server. |
target | The network object receiving an HTTP status code. |

HTTP_STATUS | Constant |
public static const HTTP_STATUS:String = "httpStatus"
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 Flash Player 9 |
The HTTPStatusEvent.HTTP_STATUS
constant defines the value of the
type
property of a httpStatus
event object.
This event has the following properties:
Property | Value |
---|---|
bubbles | false |

httpStatusHandler
event with a status of 404, indicating that
the file was not found. The httpStatusHandler
event is handled by httpStatusHandler()
,
which simply prints two lines of information about the event.
Notes:
- You need to compile the SWF file with "Local Playback Security" set
to "Access Network Only" to generate a
securityError
event in this example. - You need a server running on http://www.[yourDomain].com and listening on port 80 or you will receive
an
httpStatusHandler
event with status code 0 instead of 404. - You must not have a file named MissingFile.html at the root web directory
of http://www.[yourDomain].com or you will not receive the correct
httpStatusHandler
event.
