Issues enabling CORS with header addition

I am required to add some code to the header of my .htaccess file in folder /.well-known directory on our domain/vps, (below) it seems that Cloudflare services are affecting the outcome . Do i need change something to get this working properly?

Header set Access-Control-Allow-Origin ""


Header set Access-Control-Allow-Origin "*"

been using this to test ,

curl --head

returns this ,

HTTP/2 200

The output you are seeing shows that Cloudflare is not caching this file, and that the CORS header is not present in the response from your origin.

If you have put the Apache config in place a number of things might cause it not to work, including:

  • .htaccess being disabled (AllowOverride none in your Apache config)
  • Apache needing a reload (apachectl -k graceful)
  • mod_headers not being enabled

You can try and bypass CF in your tests directly to the Origin using this:

> curl -sD - -o /dev/null --header 'Host:' --header 'Origin:'
