Cross-Origin-Resource-Sharing with Apache for a single file doesnt work, why?

[Chris Fortmüller <chritsche@xxxxxxxxx>]

Hi, I am new to this mailiing list. I am looking for help regarding a CORS issue with my Apache Server:

I have an Appache Server (2.4) running on my machine, and would like to enable CORS for a certain file.

According to this source I need to do something like the following i my httpd.conf:

<Files "C:/xampp/htdocs/some/path/file.txt">
    Header set Access-Control-Allow-Origin "*"
</Files>

I have added this to my httpd.conf file, saved it, and restarted the server.

However, when trying to get this resource via ajax from a different network, I still get this issue:

XMLHttpRequest cannot load http://SERVERDNS.com/some/path/file.txt. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.

How can I fix this? I am not sure if I put the tag in the correct place in httpd.conf, and also I am not sure about whether the Setting itself is done correctly.

I am running this server on a Windows Server 2012 machine on the Amazon Web Services EC2 cloud.

Can anyone shed some light onto this for me?

Thanks, best regards,

Chris
