hiding source file from users

[AXH]

Hi
Is there any way to make file (on server) inaccessible for users (through web browser, ftp etc.), while still readable for applet (on the same server, launched by the same users)?

My opinion:
If the server is only HTTP, ie no servlets or cgi-bin code, then probably not. Even with some executing code on the server as above, it's a question of how to have the server code know its the applet doing the request vs a browser. You can make it difficult for the novice user to issue an HTTP get via the browser for a file by putting something in the applet's request as an identifier of the source of the request.
Another simple trick would be to encode the files and have the applet decode them. This would keep out the casual browser user.

What kind of server do you have?

apache2@ubuntu for testing, I don't know right now what server will be used later.
My applet is accessing database (mysql on the same server), and I have no idea, how to connect to database without user knowing the database password :/
