class Net_API HTTPCookie
	/// This class represents a HTTP Cookie.
	///
	/// A cookie is a small amount of information sent by a Web 
	/// server to a Web browser, saved by the browser, and later sent back 
	/// to the server. A cookie's value can uniquely identify a client, so 
	/// cookies are commonly used for session management.
	///
	/// A cookie has a name, a single value, and optional attributes such 
	/// as a comment, path and domain qualifiers, a maximum age, and a 
	/// version number.
	///
	/// This class supports both the Version 0 (by Netscape) and Version 1 
	/// (by RFC 2109) cookie specifications. By default, cookies are created 
	/// using Version 0 to ensure the best interoperability.
