Specifies whether authentication requests should be handled (true or not (false) for this request. If false, authentication challenges return an HTTP error.

The supported authentication methods are:

• Windows—HTTP Basic/Digest, Windows Integrated Authentication (including NTLM and Kerberos), SSL Certificate Authentication.
• Mac—HTTP Basic/Digest, NTLM, SSL Certificate Authentication.

Note:The FileReference.upload(), FileReference.download(), and HTMLLoader.load() methods do not support the URLRequest.authenticate property.

The default value is true.

Specifies whether successful response data should be cached for this request. When set to true, the AIR application uses the operating system's HTTP cache.

Note:The HTMLLoader.load() method does not support the URLRequest.cacheResponse property.

The default value is true.

See also

The MIME content type of the content in the the data property.

The default value is application/x-www-form-urlencoded.

Note:The FileReference.upload(), FileReference.download(), and HTMLLoader.load() methods do not support the URLRequest.contentType property.

When sending a POST request, the values of the contentType and data properties must correspond properly. The value of the contentType property instructs servers on how to interpret the value of the data property.

• If the value of the data property is a URLVariables object, the value of contentType must be application/x-www-form-urlencoded.
• If the value of the data property is any other type, the value of contentType should indicate the type of the POST data that will be sent (which is the binary or string data contained in the value of the data property).
• For FileReference.upload(), the Content-Type of the request is set automatically to multipart/form-data, and the value of the contentType property is ignored.

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.

An object containing data to be transmitted with the URL request.

This property is used in conjunction with the method property. When the value of method is GET, the value of data is appended to the value of URLRequest.url, using HTTP query-string syntax. When the method value is POST (or any value other than GET), the value of data is transmitted in the body of the HTTP request.

The URLRequest API offers binary POST support and support for URL-encoded variables, as well as support for strings. The data object can be a ByteArray, URLVariables, or String object.

The way in which the data is used depends on the type of object used:

• If the object is a ByteArray object, the binary data of the ByteArray object is used as POST data. For GET, data of ByteArray type is not supported. Also, data of ByteArray type is not supported for FileReference.upload() and FileReference.download().
• If the object is a URLVariables object and the method is POST, the variables are encoded using x-www-form-urlencoded format and the resulting string is used as POST data. An exception is a call to FileReference.upload(), in which the variables are sent as separate fields in a multipart/form-data post.
• If the object is a URLVariables object and the method is GET, the URLVariables object defines variables to be sent with the URLRequest object.
• Otherwise, the object is converted to a string, and the string is used as the POST or GET data.

This data is not sent until a method, such as navigateToURL() or FileReference.upload(), uses the URLRequest object.

Note: The value of contentType must correspond to the type of data in the data property. See the note in the description of the contentType property.

A string that uniquely identifies the signed Adobe platform component to be stored to (or retrieved from) the Flash Player cache. This property applies to SWF content only; it does not apply to JavaScript code running in AIR.

Specifies whether redirects are to be followed (true) or not (false).

Note:The FileReference.upload(), FileReference.download(), and HTMLLoader.load() methods do not support the URLRequest.followRedirects property.

The default value is true.

Specifies whether the HTTP protocol stack should manage cookies for this request. When true, cookies are added to the request and response cookies are remembered. If false, cookies are not added to the request and response cookies are not remembered, but users can manage cookies themselves by direct header manipulation.

On Mac OS, cookies are shared with Safari. To clear cookies on Mac OS:

1. Open Safari.
2. Select Safari > Preferences, and click the Security panel.
3. Click the Show Cookies button.
4. Click the Reomove All button.

To clear cookies on Windows:

1. Open the Internet Properties control panel, and click the General tab.
2. Click the Delete Cookies button.

The default value is true.

Controls the HTTP form submission method.

You can use any string value if the content is in the application security sandbox. Otherwise, you are restricted to using GET or POST operations, and valid values are URLRequestMethod.GET or URLRequestMethod.POST.

When using the navigateToURL() function, the runtime treats a URLRequest that uses the POST method (one that has its method property set to URLRequestMethod.POST) as using the GET method.

The default value is URLRequestMethod.GET.

See also

The array of HTTP request headers to be appended to the HTTP request. The array is composed of URLRequestHeader objects. Each object in the array must be a URLRequestHeader object that contains a name string and a value string, as follows:

     var rhArray:Array = new Array(new URLRequestHeader("Content-Type", "text/html"));
     

The AIR runtime imposes certain restrictions on request headers; for more information, see the URLRequestHeader class description.

Not all methods that accept URLRequest parameters support the requestHeaders property, consult the documentation for the method you are calling. For example, the FileReference.upload() and FileReference.download() methods do not support the URLRequest.requestHeaders property.

Due to browser limitations, custom HTTP request headers are only supported for POST requests, not for GET requests.

See also

The URL to be requested.

Be sure to encode any characters that are either described as unsafe in the Uniform Resource Locator specification (see http://www.faqs.org/rfcs/rfc1738.html) or that are reserved in the URL scheme of the URLRequest object (when not used for their reserved purpose). For example, use "%25" for the percent (%) symbol and "%23" for the number sign (#), as in "http://www.example.com/orderForm.cfm?item=%23B-3&discount=50%25".

By default, the URL must be in the same domain as the calling file, unless the content is running in the application security sandbox. . For more information, see the description of the URLRequest class.

Files in the application security sandobx — files installed with the AIR application — can access URLs using any of the following URL schemes:

• http and https
• file
• app-storage
• app

Note: IPv6 (Internet Protocol version 6) is supported. IPv6 is a version of Internet Protocol that supports 128-bit addresses (an improvement on the earlier IPv4 protocol that supports 32-bit addresses). You might need to activate IPv6 on your networking interfaces. For more information, see the Help for the operating system hosting the data. If IPv6 is supported on the hosting system, you can specify numeric IPv6 literal addresses in URLs enclosed in brackets ([]).

Specifies whether the local cache should be consulted before this URLRequest fetches data.

Note:The HTMLLoader.load() method does not support the URLRequest.useCache property.

The default value is true.

See also

Specifies the user-agent string to be used in the HTTP request.

Note: This property does not affect the user agent string when the URLRequest object is used with the load() method of an HTMLLoader object. To set the user agent string for an HTMLLoader object, set the userAgent property of the HTMLLoader object or set the static URLRequestDefaults.userAgent property.

Creates a URLRequest object. If System.useCodePage is true, the request is encoded using the system code page, rather than Unicode. If System.useCodePage is false, the request is encoded using Unicode, rather than the system code page.
