Description

HttpServletRequest extends the basic ServletRequest class, providing additional functionality for HTTP (World Wide Web) servlets. It includes support for cookies and session tracking and access to HTTP header information. HttpServletRequest also parses incoming HTTP form data and stores it as servlet parameters.

The server passes an HttpServletRequest object to the service method of an HttpServlet.

Certain methods in this interface have suffered from documentation and implementation inconsistencies. Discrepancies have been noted where possible.
