I have written a CGI program and I send a status error with the HTTP header to the client. but when I tried to use mod_perl it only responds with 200 ok status. How can I send a custom status code?
here is the code when I want to respond with the custom status error :
my $cgi = new CGI;
print $cgi->header(-type=>"text/html", -charset=>'utf-8', -status=>599);
EDIT :
here is the code :
#!/usr/bin/perl -w
use strict;
use warnings;
use CGI;
use SessionManagement;
my $cgi = new CGI;
my $method = $cgi->param("method");
my $sessionManagement = new SessionManagement(cgi=>$cgi);
if($sessionManagement){
if (defined($method)) {
if($method eq "authentication") {
loginMethod($cgi,$sessionManagement);
} elsif ($method eq "someMethod"){
someMethod($cgi);
} else{
print $cgi->header(-type=>"text/xml", -charset=>'utf-8');
print "<html>method does not exist</html>";
}
} else {
print $cgi->header(-type=>"text/html", -charset=>'utf-8' , -status=>599);
print "<html>blah blah</html>";
}
}else{
print $cgi->header(-type=>"text/html", -charset=>'utf-8' , -status=>599);
print "<html>blah blah</html>";
}

giving some more information:
when I use curl -v 192.168.1.212/mymodperl/test.pl
command in shell.
here is the response :

From http://www.perlmonks.org/?node_id=826769, the way to set a status code is
package My::Handler;
use strict;
use warnings 'all';
use Apache2::RequestRec;
sub handler : method {
my ($class, $r) = @_;
$r->status( 401 );
return 401;
}
1;# return true:
EDIT: Clarification
From https://perl.apache.org/docs/2.0/user/handlers/intro.html
What are Handlers?
Apache distinguishes between numerous phases for which it provides hooks (because the C functions are called ap_hook_) where modules can plug various callbacks to extend and alter the default behavior of the webserver. mod_perl provides a Perl interface for most of the available hooks, so mod_perl modules writers can change the Apache behavior in Perl. These callbacks are usually referred to as handlers and therefore the configuration directives for the mod_perl handlers look like: PerlFooHandler, where Foo is one of the handler names. For example PerlResponseHandler configures the response callback.
A typical handler is simply a perl package with a handler subroutine. For example:
file:MyApache2/CurrentTime.pm
----------------------------
package MyApache2::CurrentTime;
use strict;
use warnings;
use Apache2::RequestRec ();
use Apache2::RequestIO ();
use Apache2::Const -compile => qw(OK);
sub handler {
my $r = shift;
$r->content_type('text/plain');
$r->print("Now is: " . scalar(localtime) . "\n");
return Apache2::Const::OK;
}
1;
This handler simply returns the current date and time as a response.
Since this is a response handler, we configure it as a such in httpd.conf:
PerlResponseHandler MyApache2::CurrentTime
Since the response handler should be configured for a specific location, let's write a complete configuration section:
PerlModule MyApache2::CurrentTime
<Location /time>
SetHandler modperl
PerlResponseHandler MyApache2::CurrentTime
</Location>
Now when a request is issued to http://localhost/time this response handler is executed and a response that includes the current time is returned to the client.
