Multi-Site Subdomain: Show master site under subdomain if no sub site exists
I’ve got the following situation:
We got a WP Multisite and if a subdomain is not associated to a network site, we want wordpress to show the master site (e.g. blog ID 1) under this subdomain without a redirect.
www.domain.com --> master site of the multisite network existing.domain.com --> shows the existing blog registered under this subdomain nonexisting.domain.com --> it should show the same as www.domain.com without any redirects.
I have already changed wordpress to use root-relative URLs everywhere, so it should not matter if we are on "www" or "nonexisting" subdomain.
Thanks for your suggestions! 🙂
