       HTTP::Status - HTTP Status code processing

        use HTTP::Status qw(:constants :is status_message);

        if ($rc != HTTP_OK) {
            print status_message($rc), "\n";

        if (is_success($rc)) { ... }
        if (is_error($rc)) { ... }
        if (is_redirect($rc)) { ... }

       HTTP::Status is a library of routines for defining and classifying HTTP
       status codes for libwww-perl.  Status codes are used to encode the
       overall outcome of a HTTP response message.  Codes correspond to those
       defined in RFC 2616 and RFC 2518.

       The following constant functions can be used as mnemonic status code
       names.  None of these are exported by default.  Use the ":constants"
       tag to import them all.

       The following additional functions are provided.  Most of them are
       exported by default.  The ":is" import tag can be used to import all
       the classification functions.

       status_message( $code )
           The status_message() function will translate status codes to human
           readable strings. The string is the same as found in the constant
           names above.  If the $code is unknown, then "undef" is returned.

       is_info( $code )
           Return TRUE if $code is an Informational status code (1xx).  This
           class of status code indicates a provisional response which can't
           have any content.

       is_success( $code )
           Return TRUE if $code is a Successful status code (2xx).

       is_redirect( $code )
           Return TRUE if $code is a Redirection status code (3xx). This class
           of status code indicates that further action needs to be taken by
           the user agent in order to fulfill the request.

       is_error( $code )
           Return TRUE if $code is an Error status code (4xx or 5xx).  The
           function return TRUE for both client error or a server error status

       is_client_error( $code )
           Return TRUE if $code is an Client Error status code (4xx). This
           class of status code is intended for cases in which the client
           seems to have erred.

           This function is not exported by default.

       is_server_error( $code )
           Return TRUE if $code is an Server Error status code (5xx). This
           class of status codes is intended for cases in which the server is
           aware that it has erred or is incapable of performing the request.

           This function is not exported by default.

       For legacy reasons all the "HTTP_" constants are exported by default
       with the prefix "RC_".  It's recommended to use explict imports and the
       ":constants" tag instead of relying on this.
