I come to you because I'm facing a really strange effect on my hosting.
I currently manage a server contening a NGINX/PHP-CGI and a wordpress multisite in it.
My sites are created using subsite.domaine.tld, for now, my three subsites are correctly accessibles through the url:
My goal is to allow my subsite on the host domain to be access through their respective unique domain.
www.domainA.com would redirect to subsite1.host.domain.tld.
If I do that using the following setting on the domainA Public DNS:
www 10800 IN CNAME subsite1.host.domain.tld.
When I try to access www.domainA.com I don't go to subsite1.host.domain.tld but instead I'm redirect to the Wordpress ROOT site where I create my Network (host.domain.tld).
Is there a trick to deal with?
