I have a wordpress site, foo.com. For various reasons, mainly caching, I need to move the wp-admin area to a subdomain admin.foo.com which is hosted on a separate server.
What’s the best way to approach this, would a straight .htaccess rewirte work? I’ve seen that you can set WP_ADMIN_URL in wp-config.php but how do you separate the site in such a way that the amin sits on a different server than the rest of the site.
You can make use of two different installation of wordpress but the database will be same. One for staging and another for live
There isn’t a way to separate the frontend and admin area of a WordPress site onto two different servers. WordPress is a web application. You get the whole thing as a package.
If you’ve seen something like this before, the site owner is doing one of two things:
They are running WordPress on the admin site only, then using a plugin or some other technique to generate static HTML snapshots of the pages that form the public website.
They are using a staging site plus live site type architecture. Many of the new WP-specific hosting services include a staging site and a simple synchronization option.
