mod rewrite - Header set Access-Control-Allow-Origin in .htaccess doesn't work

Question

I can't figure out why my .htaccess header settings doesn't work.

My .htaccess file content:

Header set Access-Control-Allow-Origin *
Header always set Access-Control-Allow-Methods "POST, GET, OPTIONS, DELETE, PUT"
Header always set Access-Control-Allow-Headers "*"
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php [QSA,L]

But when I remove Header's and add them in index.php then everything works fine.

header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Methods: PUT, GET, POST, DELETE, OPTIONS");
header("Access-Control-Allow-Headers: *");

What am i missing?

Answer 1

This should work:

Header add Access-Control-Allow-Origin "*"
Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type"
Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"
