By default, the runtime looks for a socket policy file served from port As with URL policy files, this file is called the master policy file. When policy files were first introduced in Flash Player 6, there was no support for socket policy files.

Connections to socket servers were authorized by a policy file in the default location on an HTTP server on port 80 of the same host as the socket server. Flash Player 9 still supports this capability, but Flash Player 10 does not. In Flash Player 10, only socket policy files can authorize socket connections. Like URL policy files, socket policy files support a meta-policy statement that specifies which ports can serve policy files.

Access to socket and XML socket connections is disabled by default, even if the socket you are connecting to is in the same domain as the SWF file. You can permit socket-level access by serving a socket policy file from any of the following locations:. By default, Flash Player looks for a socket policy file on port and on the same port as the main socket connection. If you want to serve a socket policy file from a different port, the SWF file must call Security.

A socket policy file has the same syntax as a URL policy file, except that it must also specify the ports to which it grants access. When a socket policy file is served from a port number below , it may grant access to any ports; when a policy file comes from port or higher, it may grant access only to ports and higher.

Single port numbers, port ranges, and wildcards are accepted values. To retrieve a socket policy file from port or from the same port as a main socket connection, call the Socket.

Flash Player first checks for a master policy file on port Checks whether the EventDispatcher object has any listeners registered for a specific type of event. Indicates whether an object has a specified property defined. Indicates whether an instance of the Object class is in the prototype chain of the object specified as the parameter.

Indicates whether the specified property exists and is enumerable. Sets the availability of a dynamic property for loop operations. Returns the string representation of this object, formatted according to locale-specific conventions. Checks whether an event listener is registered with this EventDispatcher object or any of its ancestors for the specified event type.

The following example shows how you can load an external text file with URL encoded variables into an ActionScript 3. Example provided by ActionScriptExamples. The following example shows how you can load external text files.

If this parameter is omitted, no load operation begins. If specified, the load operation begins immediately see the load entry for more information. This function must accept an Event object as its only parameter and must return nothing , as this example shows: Copy. Events complete : Event — Dispatched after data has loaded successfully. This may be worked around using a policy file on the server.

SecurityError — Local untrusted files may not communicate with the Internet. This may be worked around by reclassifying this file as local-with-networking or trusted. SecurityError — You are trying to connect to a commonly reserved port. Learn more Loading external data. In the following example, an XML files is loaded and the content of its elements' first arguments are displayed in a text field.

Event Object Type: flash. Event property Event. The Event. This event has the following properties: Property Value bubbles false cancelable false ; there is no default behavior to cancel. 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. Related API Elements load.

Loads from binary data stored in a ByteArray object. The loadBytes method is asynchronous. You must wait for the "init" event before accessing the properties of a loaded object. Only the applicationDomain property of the LoaderContext object applies; the checkPolicyFile and securityDomain properties of the LoaderContext object do not apply. If the context parameter is not specified or refers to a null object, the content is loaded into the current security domain— a process referred to as "import loading" in Flash Player security documentation.

Loads an IFilePromise instance. If the data is a progressive stream, such as a video wait for the "init" or progress events before accessing the properties of the loaded object. Otherwise, wait for the complete event to make sure that the data is fully loaded. Removes a child of this Loader object that was loaded by using the load method. The property of the associated LoaderInfo object is reset to null.

The child is not necessarily destroyed because other objects might have references to it; however, it is no longer a child of the Loader object. When you call the unload method, the Loader object's contentLoaderInfo property is set to null. Any visual assets that were loaded with the SWF are unloaded and removed from memory. ActionScript class definitions in the loaded SWF remain in memory, and code in the same application domain as the loaded SWF can access instances of those classes and create new instances.

To close streams in the child SWF file, add an event listener to the child that listens for the unload event. When the parent calls Loader. The following code shows how you might do this:. This method attempts to unload SWF files that were loaded using Loader. Stage event listeners are removed. Event listeners for enterFrame , frameConstructed , exitFrame , activate and deactivate are removed.

Timers are stopped. Camera and Microphone instances are detached Movie clips are stopped. When you call the unloadAndStop method, the Loader object's contentLoaderInfo property is set to null. If you are unloading many objects asynchronously, setting the gc paramter to false might improve application performance.

However, if the parameter is set to false , media and display objects of the child SWF file might persist in memory after running the unloadAndStop command.

An EOFError exception is thrown if you attempt to read more data than is available. The httpResponseStatus event is delivered before any response data. When you build dynamic applications, it can be useful to load data from external files or from server-side scripts. This lets you build dynamic applications without having to edit or recompile your application.

Then your application can load the contents of a static text file instead of querying the database each time. The external document, params. The file contains two parameters, monthNames and dayNames. Each parameter contains a comma-separated list that is parsed as strings. You can split this list into an array using the String. If the remote document contains name-value pairs, you can parse the data using the URLVariables class by passing in the contents of the loaded file, as follows:.

Each name-value pair from the external file is created as a property in the URLVariables object. Each property within the variables object in the previous code sample is treated as a string. If the value of the name-value pair is a list of items, you can convert the string into an array by calling the String. The three possible values for the URLLoader. The following code demonstrates how setting the URLLoader.

When the file has completely downloaded, the Event. A server-side script can process the user name and password, validate it against a database, and return confirmation of whether the user-supplied credentials are valid. The following snippet creates a URLVariables object named variables, which creates a new variable called name. Adobe Flash Platform. Property Description followRedirects Specifies whether redirects are to be followed true , the default value or not false.

It is not supported in Flash Player. URI schemes The standard URI schemes, such as the following, can be used in requests made from any security sandbox: http: and https: Use these for standard Internet URLs in the same way that they are used in a web browser. Loading data from external documents When you build dynamic applications, it can be useful to load data from external files or from server-side scripts.
