title: Uploading file from one server to another (via HTTP POST)
body: <p>I have an Apache server running on a client's computer, with PHP installed. I have scheduled a task to automatically create a database backup, and it's working fine. But it makes no sense keeping the backups on the same HD the system's running, so I have to send it somewhere else.</p>
  
  <p>At first, I tried doing a PHP FTP Upload, but the client's firewall's blocking all FTP connections, and I cannot unblock it (his company won't allow me).</p>
  
  <p>Then, I tried sending the backup using SMTP, to an e-mail account. Also didn't work. All SMTP connections are also blocked (I know...).</p>
  
  <p>I'm trying now to access a webpage (on my server), via a HTTP POST REQUEST, with the file attached on the page-header. It should be possible, seeing that's pretty much what the browser does, with a file-input object, right? I just sends the multipart/data using the page header.</p>
  
  <p>Will I have to create the page header manually? Or are there any scripts that already do that?</p>
