NAME
       HTTP::Status - HTTP Status code processing

SYNOPSIS
        use HTTP::Status;

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

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

DESCRIPTION
       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.

FUNCTIONS
       The following additional functions are provided.  Most of them are
       exported by default.

       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.  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.

       is_redirect( $code )
           Return TRUE if $code is a Redirection status code. 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.  The function return
           TRUE for both client error or a server error status codes.

       is_client_error( $code )
           Return TRUE if $code is an Client Error status code. 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. 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.

BUGS
       Wished @EXPORT_OK had been used instead of @EXPORT in the beginning.
       Now too much is exported by default.
