Access-Control-Allow-Origin Multiple Origin Domains?
.htaccess, cors, cross-domain, http, xmlhttprequest
Solution
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>
Problem
Is there a way to allow multiple cross-domains using the `Access-Control-Allow-Origin` header? I'm aware of the `*`, but it is too open. I really want to allow just a couple domains. As an example, something like this: ``` Access-Control-Allow-Origin: http://domain1.example, http://domain2.example ``` I have tried the above code but it does not seem to work in Firefox. Is it possible to specify multiple domains or am I stuck with just one?
