101HTTP::Status - HTTP Status code processing
102
103=head1 SYNOPSIS
104
105 use HTTP::Status;
106
107 if ($rc != RC_OK) {
108 print status_message($rc), "\n";
109 }
110
111 if (is_success($rc)) { ... }
112 if (is_error($rc)) { ... }
113 if (is_redirect($rc)) { ... }
114
115=head1 DESCRIPTION
116
117I<HTTP::Status> is a library of routines for defining and
118classifying HTTP status codes for libwww-perl. Status codes are
119used to encode the overall outcome of a HTTP response message. Codes
120correspond to those defined in RFC 2616 and RFC 2518.
121

178=head1 FUNCTIONS
179
180The following additional functions are provided. Most of them are
181exported by default.
182
183=over 4
184
185=item status_message( $code )
186
187The status_message() function will translate status codes to human
188readable strings. The string is the same as found in the constant
189names above. If the $code is unknown, then C<undef> is returned.
190
191=item is_info( $code )
192
193Return TRUE if C<$code> is an I<Informational> status code. This
194class of status code indicates a provisional response which can't have
195any content.
196
197=item is_success( $code )
198
199Return TRUE if C<$code> is a I<Successful> status code.
200
201=item is_redirect( $code )
202
203Return TRUE if C<$code> is a I<Redirection> status code. This class of
204status code indicates that further action needs to be taken by the
205user agent in order to fulfill the request.
206
207=item is_error( $code )
208
209Return TRUE if C<$code> is an I<Error> status code. The function
210return TRUE for both client error or a server error status codes.
211
212=item is_client_error( $code )
213
214Return TRUE if C<$code> is an I<Client Error> status code. This class
215of status code is intended for cases in which the client seems to have
216erred.
217
218This function is B<not> exported by default.
219
220=item is_server_error( $code )
221
222Return TRUE if C<$code> is an I<Server Error> status code. This class
223of status codes is intended for cases in which the server is aware
224that it has erred or is incapable of performing the request.
225
226This function is B<not> exported by default.

230=head1 BUGS
231
232Wished @EXPORT_OK had been used instead of @EXPORT in the beginning.
233Now too much is exported by default.
