It's possible that mod_headers is not installed on your server, or that you're not allowed to use it. You might want to ask your host about it.

Take a look at your server error log -- It may have a specific error entry indicating whether mod_headers is available.

ok, thanks i think it's not installed - can i activate it like mod_rewrite? can i see it in the phpinfo?

Yes, you need to add it by editing httpd.conf to enable it.
