Well... i´m using LWP module to download a txt file, but needs to download only the latest 1000 bytes, i read that it can be possible using Range Bytes http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.35 But i don´t know how to setup it into the code to do my objective, i´m very noob with perl and i´m searching for help. Thanks in advance. Merry christmass. 
#!/usr/bin/perl -w
use strict;
use LWP::UserAgent;
use HTTP::Request;

my $ua = LWP::UserAgent->new;
$ua->agent("Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt)");
my $timeout = 30;

my $url = 'http://localhost/log.txt';

print "Downloading log: " ,$url , "\n";
my $req = HTTP::Request->new(GET => $url);
#$req->header(¿?¿?¿?¿?¿?);
my $response = $ua->request($req);
my $content = $response->content();

open SOURCE, '>>', 'log.txt' or die $!;
print SOURCE $content;
