Allows you to use WP behind URL rewriting balancers/proxies

wp-xforwardedhost

This mu-plugin checks the X_FORWARDED_HOST Header Field and uses it as HTTP_HOST if set. Use wp-xforwardedhost if your requests don't reach your backend with the frontend base URL (e.g. pseudo subfolder domains, rewrited in load balancers/proxies).

Installation

1. Create a directory 'mu-plugins' under wp-content
2. Put wp-xforwardedhost.php into it (double check file permissions)
3. Customize the valid_hosts array in line 12

valid_hosts check

If you want to check X_FORWARDED_HOST against a list of valid hostnames (recommended), please fill in your hostnames (comma separated) in the valid_hosts array. Notice that there shouldn't be a comma after the last element!
