Yes, I understand. (understanding english is no prob for me, other than writing). Or did you mean the PHP-Code? ;-)
But as I wrote, i knew about manipulating the headers. But your hint is very welcome -> I don't have to google... So I will fix that.
And now about adding this to TP:
the mod is not that heavy. But what is about netiquette. What about promoting files from other servers (ok, that servers and their traffic might be paid by you as well)? But is there a chance of misusing that feature? (ok, any admin will see your referrer in his logs)
What are you thinking?
