So I guess my question is, what do I replace that line of code with so it only gets the last 128 bytes?

RFC2068 (HTTP/1.1) describes a partial-content protocol. If a response comes back with "Accept-Ranges: bytes" then you may ask for "Range: bytes=-128" in a request, and get just the last 128 bytes. That'd be like this:

my $url = "http://www.server.com/filename.mp3";
use LWP::UserAgent;
my $ua = LWP::UserAgent->new;
use HTTP::Request::Common;
my $response = $ua->simple_request(GET $url, Range => 'bytes=-128');
if ($response->is_success) {
  print "last 128 bytes is: ", substr($response->content, -128), "\n";
  print "(although entire content was retrieved)\n" if length ($respon
+se->content) > 128;
}

Note that if the range request is not honored, you'll get back the entire content instead. If you wanted, you can probe first to see if the "Accept-ranges" header is in the response for that particular URL.

HTTP does not have a facility like FTP's RESTORE afaik. I think you'll have to get the whole thing.

What rpc says ... if you are on good terms with the people running the server, you might ask them kindly could they do this indexing themselves, and make the mp3 tags available to you. Otherwise, you're going to have to grab the whole thing.

Update Looky how tye's answer was the one I ended up suggesting =)
