Hello, I am brand new to perl. I am trying to create a perl script that will loggin to phpbb and post a message on a forum. Based on what I have found on the internet, this is what I have come up with.

This is the login url:
http://news.phxlab.honeywell.com/phpbb/login.php

And I believe this is important information:
<form action="login.php" method="post" target="_top">

This is the ultimate URL I want to get to:
http://news.phxlab.honeywell.com/phpbb/posting.php?mode=newtopic&f=12

And again, important information:
<form action="posting.php" method="post" name="post" onsubmit="return checkForm(this)">

Finally, here is the non-wroking code I have so far:

use strict;
use HTTP::Cookies;
use LWP::UserAgent;
use HTTP::Request::Common;

my $ua = LWP::UserAgent->new;
$ua->cookie_jar(HTTP::Cookies->new(file => "cookie2.txt",autosave => 1
+,));
my $url_base = "http://news.phxlab.honeywell.com/phpbb/posting.php?mod
+e=newtopic&f=12";
my $response = $ua->get($url_base);
#print $response->content;
my $request = HTTP::Request->new(POST=>'http://news.phxlab.honeywell.c
+om/phpbb/login.php?sid=725b728e071beec160e85c81d048a151');
$request->authorization_basic('username', 'password');
my $response = $ua->request($request);
my $content = $response->content;
$content =~ s/\n//g;#extracting session id

{
    print $response->content;  # or whatever
    #print $content;
    
}

Any help you can offer will be much appreciated. Also, if you could sort of explain what's going on, that would help to. Thanks.
