flash.net.URLRequestDefaults - Adobe® Flex® 4 Language Reference (Flex 4)

Package	flash.net
Class	public class URLRequestDefaults
Inheritance	URLRequestDefaults Object

Runtime Versions:

AIR 1.0

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 Adobe^® AIR^® 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.

Property Detail

authenticate

property

authenticate:Boolean

Runtime Versions:

AIR 1.0

The default setting for the authenticate property of URLRequest objects. Setting the authenticate 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.

Implementation
public static function get authenticate():Boolean
public static function set authenticate(value:Boolean):void

Throws

SecurityError — The caller is not in the AIR application security sandbox.

See also

URLRequest.authenticate

cacheResponse

property

cacheResponse:Boolean

Runtime Versions:

AIR 1.0

The default setting for the cacheResponse property of URLRequest objects. Setting the cacheResponse property in a URLRequest object overrides this default setting. When set to true, the default behavior for the AIR application is to use the operating system's HTTP cache. This setting does not apply to URLRequest objects used in file upload or RTMP requests.

The default value is true.

Implementation
public static function get cacheResponse():Boolean
public static function set cacheResponse(value:Boolean):void

Throws

SecurityError — The caller is not in the AIR application security sandbox.

See also

URLRequest.cacheResponse

followRedirects

property

followRedirects:Boolean

Runtime Versions:

AIR 1.0

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.

Implementation
public static function get followRedirects():Boolean
public static function set followRedirects(value:Boolean):void

Throws

SecurityError — The caller is not in the AIR application security sandbox.

See also

URLRequest.followRedirects

manageCookies

property

manageCookies:Boolean

Runtime Versions:

AIR 1.0

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.

Implementation
public static function get manageCookies():Boolean
public static function set manageCookies(value:Boolean):void

Throws

SecurityError — The caller is not in the AIR application security sandbox.

See also

URLRequest.manageCookies

useCache

property

useCache:Boolean

Runtime Versions:

AIR 1.0

The default setting for the useCache property of URLRequest objects. Setting the useCache 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.

Implementation
public static function get useCache():Boolean
public static function set useCache(value:Boolean):void

Throws

SecurityError — The caller is not in the AIR application security sandbox.

See also

URLRequest.useCache

userAgent

property

userAgent:String

Runtime Versions:

AIR 1.0

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:

"Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en) AppleWebKit/526.9+ (KHTML, like Gecko) AdobeAIR/1.5"
"Mozilla/5.0 (Windows; U; en) AppleWebKit/526.9+ (KHTML, like Gecko) AdobeAIR/1.5"
"Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/526.9+ (KHTML, like Gecko) AdobeAIR/1.5"

Implementation
public static function get userAgent():String
public static function set userAgent(value:String):void

Throws

SecurityError — The caller is not in the AIR application security sandbox.

Method Detail

setLoginCredentialsForHost

()

method

public static function setLoginCredentialsForHost(hostname:String, user:String, password:String):*

Runtime Versions:

AIR 1.0

Sets default user and password credentials for a selected host. These settings apply for URLRequest objects in all application domains of the application, not only those in the application domain of the object calling this method (whereas the static properties of the URLRequest class apply to the caller's application domain only). This allows content in the entire application (regardless of the content's application domain) to be logged in when another part of the application logs in.

Note for applications running on Mac OS: On Mac OS, when you call this method, the application uses these credentials for the specified host until the application is closed, even if you subsequently call URLRequestDefaults.setLoginCredentialsForHost() for the same host. However, if a server rejects the credentials specified by this method, then a subsequent call to the URLRequestDefaults.setLoginCredentialsForHost() method (for the same host) will be recognized.

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

Parameters

	`hostname:String` — The host name to which the user name and password are applied. This can be a domain, such as `"www.example.com"` or a domain and a port number, such as `"www.example.com:80"`. Note that `"example.com"`, `"www.example.com"`, and `"sales.example.com"` are each considered unique hosts.

	`user:String` — The default user name to use in request authentication for the specified host.

	`password:String` — The default password to use in request authentication for the specified host.

Returns

*

Throws

SecurityError — The caller is not in the AIR application security sandbox.
