An opaque key-value value pair held by an HTTP client to permit a stateful session with an HTTP server. This class parses cookie headers for all three commonly used HTTP cookie specifications:

• The Netscape cookie spec is officially obsolete but widely used in practice. Each cookie contains one key-value pair and the following attributes: Domain, Expires, Path, and Secure. The HttpCookie.Version of cookies in this format is 0. There are no accessors for the Expires attribute. When parsed, expires attributes are assigned to the HttpCookie.MaxAge attribute as an offset from Java.Lang.JavaSystem.CurrentTimeMillis.
• formalizes the Netscape cookie spec. It replaces the Expires timestamp with a Max-Age duration and adds Comment and Version attributes. The HttpCookie.Version of cookies in this format is 1.
• refines RFC 2109. It adds Discard, Port, and CommentURL attributes and renames the header from Set-Cookie to Set-Cookie2. The HttpCookie.Version of cookies in this format is 1.

Support for the "HttpOnly" attribute specified in is also included. RFC 6265 is intended to obsolete RFC 2965. Support for features from RFC 2965 that have been deprecated by RFC 6265 such as Cookie2, Set-Cookie2 headers and version information remain supported by this class.

This implementation silently discards unrecognized attributes.
