  Chapter: Overview

  description:
  This header-file describes the C++-API for the WebAgent. This API
  can be used to write services (WebAgent User DLL's) that handle
  incoming HTTP requests. The WebAgent API is web server independent.
  Services using this API work with the web servers from Microsoft, 
  Netscape and the Apache. For other servers the standard CGI protocol
  can be used.

  This API includes classes for HTTP request handling (WAHttpRequest),
  writing HTTP responses (WAHttpResponse), session management
  (WAWebSession) and other stuff (WAWebAgent). The class WAErr is used
  to retrieve error information if an operation failed. */

                     The date string is formatted in WebAgent date-format:
                     YYYYMMDDHHMMSS. It is always spefified in
                     timezone GMT.

                     expires is an optional attribute. If it is NULL
                     or empty, the cookie will expire when the user's
                     session ends.
        path    [IN] The path attribute is used to specify the subset
                     of URLs in a domain for which the cookie is
                     valid. If a cookie has already passed domain
                     matching, then the pathname component of the URL
                     is compared with the path attribute, and if there
                     is a match, the cookie is considered valid and is
                     sent along with the URL request. The path "/foo"
                     would match "/foobar" and "/foo/bar.html". The
                     path "/" is the most general path.

                     If the path is NULL, it as assumed to be the same
                     path as the document being described by the header
                     which contains the cookie.
        domain  [IN] When searching the cookie list for valid cookies,
                     a comparison of the domain attributes of the
                     cookie is made with the Internet domain name of
                     the host
                     from which the URL will be fetched. If there is a
                     tail match, then the cookie will go through path
                     matching to see if it should be sent. "Tail
                     matching" means that domain attribute is matched
                     against the tail of the fully qualified domain
                     name of the host. A domain attribute of
                     "acme.com" would match host names
                     "anvil.acme.com" as well as
                     "shipping.crate.acme.com".
                     Only hosts within the specified domain can set a
                     cookie for a domain and domains must have at
                     least two (2) or three (3) periods in them to
                     prevent domains of the form: ".com", ".edu", and
                     "va.us". Any domain that fails within one of the
                     seven special top level domains listed below only
                     require two periods. Any other domain requires at
                     least three. The seven special top level domains
                     are: "COM", "EDU", "NET", "ORG", "GOV", "MIL",
                     and "INT".

                     If domain is NULL the host name of
                     the server which generated the cookie response is
                     used.
        secure  [IN] If a cookie is marked secure, it will only be
                     transmitted if the communications channel with
                     the host is a secure one. Currently this means
                     that secure cookies will only be sent to HTTPS
                     (HTTP over SSL) servers.

                     If secure is not specified, a cookie is
                     considered safe to be sent in the clear over
                     unsecured channels.
