The URLRequestDefaults class includes static properties that you can set to define default values for the properties of the URLRequest class. It also includes a static method, URLRequestDefaults.setLoginCredentialsForHost(), which lets you define default authentication credentials for requests. The URLRequest class defines the information to use in an HTTP request.

Any properties set in a URLRequest object override those static properties set for the URLRequestDefaults class.

URLRequestDefault settings only apply to content in the caller's application domain, with one exception: settings made by calling URLRequestDefaults.setLoginCredentialsForHost() apply to all application domains in the currently running application.

Only AdobeĀ® AIRĀ® content running in the application security sandbox can use the URLRequestDefaults class. Other content will result in a SecurityError being thrown when accessing the members or properties of this class.

Static variables

staticfollowRedirects:Bool = true

The default setting for the followRedirects property of URLRequest objects. Setting the followRedirects property in a URLRequest object overrides this default setting. This setting does not apply to URLRequest objects used in file upload or RTMP requests.

The default value is true.

staticidleTimeout:Float = 0

The default setting for the idleTimeout property of URLRequest objects and HTMLLoader objects.

The idle timeout is the amount of time (in milliseconds) that the client waits for a response from the server, after the connection is established, before abandoning the request.

This defines the default idle timeout used by the URLRequest or HTMLLoader object. Setting the idleTimeout property in a URLRequest object or an HTMLLoader object overrides this default setting.

When this property is set to 0 (the default), the runtime uses the default idle timeout value defined by the operating system. The default idle timeout value varies between operating systems (such as Mac OS, Linux, or Windows) and between operating system versions.

This setting does not apply to URLRequest objects used in file upload or RTMP requests.

The default value is 0.

staticmanageCookies:Bool = false

The default setting for the manageCookies property of URLRequest objects. Setting the manageCookies property in a URLRequest object overrides this default setting.

Note: This setting does not apply to URLRequest objects used in file upload or RTMP requests.

The default value is true.

staticuserAgent:String

The default setting for the userAgent property of URLRequest objects. Setting the userAgent property in a URLRequest object overrides this default setting.

This is also the default user agent string for all HTMLLoader objects (used when you call the load() method of the HTMLLoader object). Setting the userAgent property of the HTMLLoader object overrides the URLRequestDefaults.userAgent setting.

This default value varies depending on the runtime operating system (such as Mac OS, Linux or Windows), the runtime language, and the runtime version, as in the following examples:
