The HttpJspPage interface is implemented by the Servlet class representing all HTTP JSP pages. It defines the _jspService() method, which is called by the JSP container to generate the page content.

_jspService() provides an HTTP protocol-specific implementation of the JSP service() method. This method is generated automatically by the JSP processor based on the contents of the JSP page.
