   AUTH_TYPE

      This variable is specific to requests made with HTTP.

      If the script URI would require access authentication for external
      access, then this variable is found from the `auth-scheme' token
      in the request, otherwise NULL.

         AUTH_TYPE   = "" | auth-scheme

         auth-scheme = "Basic" | token

      HTTP access authentication schemes are described in section 11 of
      the HTTP/1.0 specification [3]. The auth-scheme is not
      case-sensitive.

   CONTENT_LENGTH

      The size of the entity attached to the request, if any, in decimal
      number of octets. If no data is attached, then NULL. The syntax is
      the same as the HTTP Content-Length header (section 10, HTTP/1.0
      specification [3]).

         CONTENT_LENGTH = "" | [ 1*digit ]

   CONTENT_TYPE

      The Internet Media Type [9] of the attached entity. The syntax is
      the same as the HTTP Content-Type header.

         CONTENT_TYPE = "" | media-type
         media-type   = type "/" subtype *( ";" parameter)
         type         = token
         subtype      = token
         parameter    = attribute "=" value
         attribute    = token
         value        = token | quoted-string

      The type, subtype and parameter attribute names are not
      case-sensitive. Parameter values may be case sensitive.  Media
      types and their use in HTTP are described section 3.6 of the
      HTTP/1.0 specification [3]. Example:

         application/x-www-form-urlencoded

      There is no default value for this variable. If and only if it is
      unset, then the script may attempt to determine the media type
      from the data received. If the type remains unknown, then
      application/octet-stream should be assumed.

   GATEWAY_INTERFACE

      The version of the CGI specification to which this server
      complies.  Syntax:

         GATEWAY_INTERFACE =  "CGI" "/" 1*digit "." 1*digit

      Note that the major and minor numbers are treated as separate

      integers and that each may be incremented higher than a single
      digit.  Thus CGI/2.4 is a lower version than CGI/2.13 which in
      turn is lower than CGI/12.3. Leading zeros must be ignored by
      scripts and should never be generated by servers.

      This document defines the 1.1 version of the CGI interface.
