Simple search would have give you some answers using :
perldoc LWP:/UserAgent or HTTP::Request
Super Search
Cookbook

Or from the lwpcook (via this Davorg's post):

use HTTP::Request::Common qw(POST);
use LWP::UserAgent;
$ua = new LWP::UserAgent;
my $req = POST 'http://www.perl.com/cgi-bin/BugGlimpse',
                [ search => 'www', errors => 0 ];
print $ua->request($req)->as_string;

Now to answer our question stay with the LWP beccause it's powerful AND easy !!!
