Re: first steps with mod_perl

Hi Gunnar,

if I understand well, it is extremely difficult to make CGI.pm produce
valid html

My problem are the many <p /> tags in the form - and the checked
instead of checked="checked" in the input-tags. But probably I am not
yet understanding CGI.pm?

Probably it is really easier, to print directly avoiding CGI.pm, as
Gunnar suggested?


Greetings to all

My example-script looks now like follows:

#! /usr/bin/perl -wT

use strict;
use CGI::Carp qw(warningsToBrowser fatalsToBrowser);
use CGI qw/:standard/;
use Socket;
