I have a script that reads one of my pages to test it. the page it tests, will redirect to a number of different urls.

I use LWP to contact the page and get me the html of the page it loads. Some of them are identical source code.

I need to know what URL it is redirecting to.
How can I get that from LWP?

Here is my code:

    my $ua = LWP::UserAgent->new;
    $ua->agent("Mozilla/8.0");
    $ua->cookie_jar(HTTP::Cookies->new(file => "lwpcookies.txt",
                                     autosave => 1));
    
    push @{$ua->requests_redirectable}, 'GET';
    my $req = HTTP::Request->new(GET => "$_fileLoc");
    $req->referer($_fileLoc);
  # Pass request to the user agent and get a response back
    $res = $ua->request($req);
    print $res->status_line, "\n";
    if($res->status_line =~ /404 Not Found/i) {
        $_bad++;
    } else {
        if($res->is_success) {
            print $res->is_success, "\n";
            if($res->status_line =~ /404 Not Found/i) {
                $_bad++;
            } else {
                $_cn = $res->content;
                print $_cn, "\n";
            }
        } else {
            $_bad1++;
            $_errorT = $res->status_line;
            print qq~error: "~ . $_errorT . '"'. \t;#'
        }
    }

that is a section of my code.
How can I get this to only tell me the URL it redirected to? not the url it ended up on, but where it redirected to, like this: header("Location: http://mydomain.com/path1/someotherpath.php"); have it give me the redirected url: http://mydomain.com/path1/someotherpath.php, because someotherpath.php would also redirect to one other location, so I need the first one.

Can someone tell me how to do this?

Thank you.
