HttpServletRequest
Synopsis
Interface Name:
javax.servlet.http.HttpServletRequest
Superinterface: javax.servlet.ServletRequest
Immediate Subinterfaces: None
Implemented By: None
Availability: Servlet API 1.0 and later
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.
