  	@header CaptiveNetwork
  	@discussion The CaptiveNetwork API allows applications to interact
  		with Captive Network Support. Captive Network Support is a
  		system component responsible for detecting and help users
  		navigate networks that require interaction before providing
  		internet access. The most common Captive Networks are WiFi
  		Hotspots in places like airports, restaurants, and hotels.
  		Captive Network Support will attempt to authenticate if
  		possible or drop a user in to a web sheet if authentication
  		is not possible. In the web sheet the user has an opportunity
  		to authenticate or disassociate from the network.
  
  		The following APIs are designed for third party applications
  		that may handle authentication on these networks on behalf of
  		the user.
  
  		These APIs are treated as advisory only.
  		There is no guarantee or contract that the operating system
  		will take the intended action.
