    See RFC 3875 for the CGI spec, which has all the info you need. 🙂

    From the RFC:

      meta-variable-name = "AUTH_TYPE" | "CONTENT_LENGTH" |
                       "CONTENT_TYPE" | "GATEWAY_INTERFACE" |
                       "PATH_INFO" | "PATH_TRANSLATED" |
                       "QUERY_STRING" | "REMOTE_ADDR" |
                       "REMOTE_HOST" | "REMOTE_IDENT" |
                       "REMOTE_USER" | "REQUEST_METHOD" |
                       "SCRIPT_NAME" | "SERVER_NAME" |
                       "SERVER_PORT" | "SERVER_PROTOCOL" |
                       "SERVER_SOFTWARE" | scheme |
                       protocol-var-name | extension-var-name
  protocol-var-name  = ( protocol | scheme ) "_" var-name
  scheme             = alpha *( alpha | digit | "+" | "-" | "." )
  var-name           = token
  extension-var-name = token
