Access-Control-Allow-Origin Multiple Origin Domains?
Another solution I'm using in PHP:
$http_origin = $_SERVER['HTTP_ORIGIN'];
if ($http_origin == "http://www.domain1.com" || $http_origin == "http://www.domain2.com" || $http_origin == "http://www.domain3.com")
{
header("Access-Control-Allow-Origin: $http_origin");
}
Sounds like the recommended way to do it is to have your server read the Origin header from the client, compare that to the list of domains you would like to allow, and if it matches, echo the value of the Origin
header back to the client as the Access-Control-Allow-Origin
header in the response.
With .htaccess
you can do it like this:
# ----------------------------------------------------------------------
# Allow loading of external fonts
# ----------------------------------------------------------------------
<FilesMatch "\.(ttf|otf|eot|woff|woff2)$">
<IfModule mod_headers.c>
SetEnvIf Origin "http(s)?://(www\.)?(google.com|staging.google.com|development.google.com|otherdomain.example|dev02.otherdomain.example)$" AccessControlAllowOrigin=$0
Header add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
Header merge Vary Origin
</IfModule>
</FilesMatch>
