NAME

       HTTP::Status - HTTP Status code processing

SYNOPSIS

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

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

	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.

CONSTANTS

       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.

	  HTTP_CONTINUE 		       (100)
	  HTTP_SWITCHING_PROTOCOLS	       (101)

FUNCTIONS

       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
	   codes.

       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.

BUGS

       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.
