handle multiple domains with Access-Control-Allow-Origin header in Apache

Question

I want to configure apache for cross-domain access header. I have tried multiple combination as suggested on number of threads on the forum. But its not working for me.

The ways, I have tried:

1) Specify domain on different line as below with Header set :

Header set Access-Control-Allow-Origin "example1.com" Header set Access-Control-Allow-Origin "example2.com" Header set Access-Control-Allow-Origin: "example3.com" 

With this setup its picking only last one and ignore rest of all.

2) Specify domain on different line as below with Header add :

Header add Access-Control-Allow-Origin "example1.com" Header add Access-Control-Allow-Origin "example2.com" Header add Access-Control-Allow-Origin: "example3.com" 

With this its showing all three domains in header, but fonts are not getting picked up on Firefox.

3.) Tried Using SetEnvIf, but again its not working :

SetEnvIf Origin "http(s)?://(www\.)?(mydomain.com|mydomain2.com)$" AccessControlAllowOrigin=$0$1 Header add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin 

Finally working with "*", but I don't want to use this.

Please help with this.

For 3 domains, in your .htaccess:

<IfModule mod_headers.c>     SetEnvIf Origin "http(s)?://(www\.)?(domain1.org|domain2.com|domain3.net)$" AccessControlAllowOrigin=$0$1     Header add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin     Header set Access-Control-Allow-Credentials true </IfModule> 

I've tried this and it works for me. Let me know if it doesn't for you.
