         REMOTE_ADDR = hostnumber
         hostnumber  = digits "." digits "." digits "." digits
         digits      = 1*digit

   REMOTE_HOST

      The fully qualified domain name of the agent sending the request
      to the server, if available, otherwise NULL. Not necessarily that
      of the client. Fully qualified domain names take the form as
      described in section 3.5 of RFC 1034 [8] and section 2.1 of RFC
      1123 [5]; a sequence of domain labels separated by ".", each
      domain label starting and ending with an alphanumerical character
      and possibly also containing "-" characters. The rightmost domain
      label will never start with a digit. Domain names are not case
      sensitive.

         REMOTE_HOST   = "" | hostname
         hostname      = *( domainlabel ".") toplabel
         domainlabel   = alphadigit [ *alphahypdigit alphadigit ]
         toplabel      = alpha [ *alphahypdigit alphadigit ]
         alphahypdigit = alphadigit | "-"
         alphadigit    = alpha | digit

   REMOTE_IDENT

      The identity information reported about the connection by a RFC
      931 [10] request to the remote agent, if available. The server may
      choose not to support this feature, or not to request the data for
      efficiency reasons.

         REMOTE_IDENT = *CHAR

      The data returned is not appropriate for use as authentication
      information.

   REMOTE_USER

      This variable is specific to requests made with HTTP.

      If AUTH_TYPE is "Basic", then the user-ID sent by the client. If
      AUTH_TYPE is NULL, then NULL, otherwise undefined.

         REMOTE_USER = "" | userid | *OCTET
         userid      = token

   REQUEST_METHOD

      This variable is specific to requests made with HTTP.




 
INTERNET-DRAFT       Common Gateway Interface - 1.1     15 February 1996


      The method with which the request was made, as described in
      section 5.1.1 of the HTTP/1.0 specification [3].

         REQUEST_METHOD   = http-method
         http-method      = "GET" | "HEAD" | "POST" | extension-method
         extension-method = token

      The method is case sensitive.

   SCRIPT_NAME

      A URL path that could identify the CGI script (rather then the
      particular CGI output). The syntax and semantics are identical to
      a decoded HTTP URL `hpath' token [4].

         SCRIPT_NAME = "" | "/" [ path ]

      The leading "/" is not part of the path. It is optional if the
      path is NULL.

      The SCRIPT_NAME string is some leading part of the 
      component of the script URI derived in some implementation defined
      manner.

   SERVER_NAME

      The name for this server, as used in the  part of the script
      URI. Thus either a fully qualified domain name, or an IP address.

         SERVER_NAME = hostname | hostnumber

   SERVER_PORT

      The port on which this request was received, as used in the 
      part of the script URI.

         SERVER_PORT = 1*digit

   SERVER_PROTOCOL
