HTTP::Status - HTTP Status code processing
SYNOPSIS
use HTTP::Status;
if ($rc != RC_OK) {
print status_message($rc), "\n";

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:
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.
