Setting the user agent used when loading HTML content

Adobe AIR 1.0 and later

The HTMLLoader class has a userAgent property, which lets you set the user agent string used by the HTMLLoader. Set the userAgent property of the HTMLLoader object before calling the load() method. If you set this property on the HTMLLoader instance, then the userAgent property of the URLRequest passed to the load() method is not used.

You can set the default user agent string used by all HTMLLoader objects in an application domain by setting the URLRequestDefaults.userAgent property. The static URLRequestDefaults properties apply as defaults for all URLRequest objects, not only URLRequests used with the load() method of HTMLLoader objects. Setting the userAgent property of an HTMLLoader overrides the default URLRequestDefaults.userAgent setting.

If you do not set a user agent value for either the userAgent property of the HTMLLoader object or for URLRequestDefaults.userAgent , then the default AIR user agent value is used. This default value varies depending on the runtime operating system (such as Mac OS or Windows), the runtime language, and the runtime version, as in the following two examples:

  • "Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en) AppleWebKit/420+ (KHTML, like Gecko) AdobeAIR/1.0"

  • "Mozilla/5.0 (Windows; U; en) AppleWebKit/420+ (KHTML, like Gecko) AdobeAIR/1.0"
