I am currently working on a site that (has / is going to have) hundreds of sub sites. I am unable to give the actual links due to privacy concerns and will use fabricated sub domains / domains.
I have wwww.mainurl.com working. When I make a site it creates a subdomain off of mainurl.com (example: http://www.test.mainurl.com).
However, I need each site to have a custom url, http://www.test1.com would point to wwww.test1.mainurl.com so that http://www.test1.com is a usable link for that site.
Right now the site IS redirecting traffic to the right page. http://www.test1.com redirects to http://www.test1.mainurl.com but it shows the true url.
Is this an issue with the plugin? Or could I be handling the DNS record incorrectly?
