Re: mod_perl and CGI::Application.. Strange Behaviour

[Anthony Gardner <suppressed>]

Unless I'm missing sth, have you read the docs?

With CGI::Application, you don;t print anything, you just return whatever it is you want 'printed'

I have able to solve to maximum extent.
rectified all the errors and able to print the result. this time its
printing the http headers as well....if I turn of http headers, then nothing
is getting printed..little weird !!!

modified my httpd conf file as follows:

Config File Entry

Alias /perl /docroot/cgi-perl
PerlModule Apache::Registry

SetHandler perl-script
PerlHandler Apache::Registry
Options ExecCGI


and changed the perl module as follows:

Perl Module => First.pm

package First ;
use strict;
use base 'CGI::Application';
use CGI::Application::Plugin::Apache qw(:all);

sub setup {

my $self = shift;
$self->run_modes( 'mode1' => 'mode1_sub' );
$self->start_mode( 'mode1' );
}

sub mode1_sub {

my $self = shift;
my $req = $self->query();
$req->content_type( 'text/html' );
$req->send_http_header;

my $var = "Hello!!! Its Working
";
$req->print( $var );
}

1;

my CGI Script => first.cgi

use strict;
use First;

my $webapp = First->new();
$webapp->run();

Result

Its printing in browser along with headers as follows:

Hello!!! Its Working
HTTP/1.1 200 OK Date: Fri, 26 Oct 2007 19:45:18 GMT Server: Apache/1.3.33
(Darwin) PHP/4.3.9 mod_perl/1.26 Keep-Alive: timeout=15, max=98 Connection:
Keep-Alive, Keep-Alive Transfer-Encoding: chunked, chunked Content-Type:
text/html

I dont want to print headers so that only HTML content is shown...if I tried
to comment $req->send_http_headers; line in perl module, then nothing is
seen in the browser.

unable to figure out solution. Please help me
