Apache redirect directory to subdomain

  • 772

I'm attempting to get around some Cross Origin issues on IE11 and iOS by masking a subdomain as a directory

i.e.

I want example.com/cdn/ to actually load cdn.example.com/

I've kind of got it working with

RedirectMatch 301 ^/cdn/(.*)$ http://cdn.example.com/$1

But in the browser the redirect happens and it still shows http://cdn.example.com rather than leaving it as example.com/cdn/

Any way to achieve this!?

apache-2.2 .htaccess

    You can use mod_proxy to proxy the requests from the directory through to the actual domain:

    ProxyRequests         Off
ProxyPreserveHost     On

ProxyPass             /cdn           http://cdn.example.com
ProxyPassReverse      /cdn           http://cdn.example.com

    This has to be put in the actual apache config, it doesn't work in a .htaccess file.

    Note that by proxying the requests like this you are rendering the advantages of a CDN useless. The header solution in my other answer is preferable over this.

  2. You can add the Access-Control-Allow-Origin header to the responses your server provides.

    You can to this either in your scripts (PHP or whatever you run on the server) or you can do this in the .htaccess file using mod_headers:

    <IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "http://cdn.example.com"
</IfModule>
