[Playlist] How to avoid music download?

[José Renato]

Hi All,

I would like to know if it is possible to build a playlist avoiding 
direct file referece. Because now we have:

<?xml version="1.0" encoding="UTF-8"?>
<playlist version="1" xmlns="http://xspf.org/ns/0/">
  <trackList>
      <track><location>http://example.com/song_1.mp3</location></track>
  </trackList>
</playlist>

In that case anyone could save the playlist file and copy location. 
Finally you can download it. Is it possible to use a Java Servlet, for 
example, to delivery the mp3 content based on previous session 
information as streaming? Is there another aproach to avoid music download?

Actually I haven´t tried yet. But I was wondering if something like that 
could be used:

<?xml version="1.0" encoding="UTF-8"?>
<playlist version="1" xmlns="http://xspf.org/ns/0/">
  <trackList>
      
<track><location>https://example.com/MyServet?songId=song1</location></track> 

      
<track><location>https://example.com/MyServet?songId=song2</location></track> 

  </trackList>
</playlist>

So using https I would protect against sniffing protocol attempts. And 
with a "controler" I could distribute the song only for the user 
session. Any suggestions?

Best Regards,
José Renato.
