Looks up a class that previously had an alias registered through a call to the registerClassAlias() method.

This method does not interact with the flash.utils.getDefinitionByName() method.

Parameters

See also

Opens or replaces a window in the application that contains the Flash Player container (usually a browser).

Note: For local content running in a browser, calls to the navigateToURL() method that specify a "javascript:" pseudo-protocol (via a URLRequest object passed as the first parameter) are only permitted if the SWF file and the containing web page (if there is one) are in the local-trusted security sandbox. Some browsers do not support using the javascript protocol with the navigateToURL() method. Instead, consider using the call() method of the ExternalInterface API to invoke JavaScript methods within the enclosing HTML page.

You cannot connect to commonly reserved ports. For a complete list of blocked ports, see "Restricting Networking APIs" in the security chapter of the Programming ActionScript 3.0 book.

In Flash Player 10 and later running in a browser, using this method programmatically to open a pop-up window may not be successful. Various browsers (and browser configurations) may block pop-up windows at any time; it is not possible to guarantee any pop-up window will appear. However, for the best chance of success, use this method to open a pop-up window only in code that executes as a direct result of a user action (for example, in an event handler for a mouse click or key-press event.)

In Flash Player 10 and later, if you use a multipart Content-Type (for example "multipart/form-data") that contains an upload (indicated by a "filename" parameter in a "content-disposition" header within the POST body), the POST operation is subject to the security rules applied to uploads:

• The POST operation must be performed in response to a user-initiated action, such as a mouse click or key press.
• If the POST operation is cross-domain (the POST target is not on the same server as the SWF file that is sending the POST request), the target server must provide a URL policy file that permits cross-domain access.

Also, for any multipart Content-Type, the syntax must be valid (according to the RFC2046 standards). If the syntax appears to be invalid, the POST operation is subject to the security rules applied to uploads.

Parameters

package {
    import flash.display.Sprite;
    import flash.net.navigateToURL;
    import flash.net.URLRequest;
    import flash.net.URLVariables;

    public class NavigateToURLExample extends Sprite {

        public function NavigateToURLExample() {
            var url:String = "http://www.adobe.com";
            var variables:URLVariables = new URLVariables();
            variables.exampleSessionId = new Date().getTime();
            variables.exampleUserLabel = "Your Name";
            var request:URLRequest = new URLRequest(url);
            request.data = variables;
            try {            
                navigateToURL(request);
            }
            catch (e:Error) {
                // handle error here
            }
        }
    }
}

Preserves the class (type) of an object when the object is encoded in Action Message Format (AMF). When you encode an object into AMF, this function saves the alias for its class, so that you can recover the class when decoding the object. If the encoding context did not register an alias for an object's class, the object is encoded as an anonymous object. Similarly, if the decoding context does not have the same alias registered, an anonymous object is created for the decoded data.

LocalConnection, ByteArray, SharedObject, NetConnection and NetStream are all examples of classes that encode objects in AMF.

The encoding and decoding contexts do not need to use the same class for an alias; they can intentionally change classes, provided that the destination class contains all of the members that the source class serializes.

Parameters

package {
    import flash.display.Sprite;
    import flash.net.registerClassAlias;
    import flash.utils.ByteArray;

    public class RegisterClassAliasExample extends Sprite {
        public function RegisterClassAliasExample() {
            registerClassAlias("com.example.eg", ExampleClass);
            var eg1:ExampleClass = new ExampleClass();
            var ba:ByteArray = new ByteArray();
            ba.writeObject(eg1);
            ba.position = 0;
            var eg2:* = ba.readObject();
            trace(eg2 is ExampleClass); // true
        }
    }
}

class ExampleClass {}

Sends a URL request to a server, but ignores any response.

To examine the server response, use the URLLoader.load() method instead.

You cannot connect to commonly reserved ports. For a complete list of blocked ports, see "Restricting Networking APIs" in the security chapter of the Programming ActionScript 3.0 book.

You can prevent a SWF file from using this method by setting the allowNetworking parameter of the the object and embed tags in the HTML page that contains the SWF content.

In Flash Player 10 and later, if you use a multipart Content-Type (for example "multipart/form-data") that contains an upload (indicated by a "filename" parameter in a "content-disposition" header within the POST body), the POST operation is subject to the security rules applied to uploads:

• The POST operation must be performed in response to a user-initiated action, such as a mouse click or key press.
• If the POST operation is cross-domain (the POST target is not on the same server as the SWF file that is sending the POST request), the target server must provide a URL policy file that permits cross-domain access.

Also, for any multipart Content-Type, the syntax must be valid (according to the RFC2046 standards). If the syntax appears to be invalid, the POST operation is subject to the security rules applied to uploads.
