upload to another directory

I've downloaded an upload script from perlscriptsjavascripts.com, and it all works fine. However, I want the files to be uploaded to another host then the host where the script is located. How do I do that?

This is the script:

Code:

#!/usr/bin/perl --
# 'accountname' has of course another name in the real script. Already tried to change this to the root directory of the other host, but that doesn't seem to work: my script begins to complain I should exactly enter the correct root dir.
$dir = "/home/accountname/www";
# absolute URL to folder files will be uploaded to
# I changed the host for a x because of security reasons. Already tried to change this path to the name of the uploadhost, just as the above $dir var, but it doesn't work.
$folder = "http://x/";
$max = 500;
$domain = "http://x/";
$redirect = "";
$notify = '';
$send_mail_path = "";
$smtp_path = "";
# set to 1 if you would like all files in the directory printed to the web page
# after a successful upload (only printed if redirect is off). Set to 0 if you
# do not want filenames printed to web page
$print_contents = 1;
$overwrite = 0;
# file types allowed, enter each type on a new line
# Enter the word "ALL" in uppercase, to accept all file types.
@types = qw~
txt
jpeg
jpg
gif
~;
# well, everything above was pretty clare to me, but below this line, most of it is totally bogus.
$folder =~ s/(\/|\\)$//ig;
$OS = $^O; # operating system name
if($OS =~ /darwin/i) { $isUNIX = 1; }
elsif($OS =~ /win/i) { $isWIN = 1; }
else {$isUNIX = 1;}
if($isWIN){ $S{S} = "\\\\"; }
else { $S{S} = "/";} # seperator used in paths
$ScriptURL = "http://$ENV{'SERVER_NAME'}$ENV{'SCRIPT_NAME'}";
unless (-d "$dir"){
mkdir ("$dir", 0777); # unless the dir exists, make it ( and chmod it on UNIX )
chmod(0777, "$dir");
}
unless (-d "$dir"){
# if there still is no dir, the path entered by the user is wrong and the upload will fail
&PrintHead; #print the header
# get the Win root
$ENV{PATH_INFO} =~ s/\//$S{S}/gi;
$ENV{PATH_TRANSLATED} =~ s/$ENV{PATH_INFO}//i;
print qq~
<table width="600">
<tr>
<td>
<font face="Arial" size="2">
<b>The path you entered is incorrect.</b> You entered : "$dir"
<p>
Your root path is (UNIX): $ENV{DOCUMENT_ROOT}
<p>
Your root path is (WINDOWS): $ENV{PATH_TRANSLATED}
<p>
Your path should contain your root path followed by a slash followed by the
destination folder's name. If you are on a WINDOWS server, each slash should
be escaped. Eg. each seperator should look like this : \\\\
<p>
Sometimes, the root returned is not the full path to your web space. In this case
you should either check with your host or if you are using an FTP client such as
CuteFTP, change to the folder you are trying to upload to and look at the path you
have taken. You can see this just above the list of files on your server.
You must use the same path in the \$dir variable.
