Question
What is the proper way to setup the redirects / handle SSL? When I add a simple 301 redirect record into my DNS, it complains about mismatched SSL certificates when you click an old link like https://child-company-a.com and it redirects to the new Webflow site that has a different SSL certificate.
You may need to enter some A and CNAME records in order to enable Cloudflare’s proxy feature, which is needed for page rules. If so you, can just use Webflow’s settings, e.g.;
Page rules are powerful, and support wildcards, so if you really wanted to, you can support path mapping, e.g.;
A request to https://child-company-a.com/product/something could be redirected to https://parentcompany.com/child-company-a/product/something.
Yes I believe that’s correct, but don’t worry, it’s not relevant here. Your child-company* domains don’t actually link to, and Webflow isn’t even aware of them. You simply do not put them in your Webflow site hosting settings, only parent-company.com.
Cloudflare redirects requests to your child-company* domains to parent.company.com, and Webflow is not involved.
