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.

Answer 1

I am using this in my .htaccess file for allowing access to multiple domains

 <ifModule mod_headers.c>
    SetEnvIf Origin "http(s)?://(localhost:25120|domain.com|domain2.com)$" AccessControlAllowOrigin=$0
    Header add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
    Header always set Access-Control-Allow-Methods: "GET,POST,OPTIONS,DELETE,PUT"
 </ifModule>    

Answer 2

For Apache 2.4, I have used SET command for the Apache web server to set Header dynamically.

<IfModule mod_deflate.c>
  # CORS
  SetEnvIfNoCase Origin "http(s)?://(\w+\.)?(example.com|localhost)(:[0-9]+)?$" AccessControlAllowOrigin=$0
  Header set Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
  Header set Access-Control-Allow-Credentials true
</IfModule>

ADD command didn't work for me.
