You have an SSH access on rented host?
That is a rare flower khaha... So, off topics,
you can access all folders on server, or just your folder?
As I said, I am not quite sure of right answer... But if it works I wouldn't mess with it, hehe...
I do believe that aj_nsc's approach is the right one,
if I had my server(s) I surly would not have c-panel,
so I would go aj_nsc's way.
As I tried to do that way on my paid host (FTP) it had no effect.
As I poked around I found out that I can set MIME types in my c-panel.
And that now works.
