How do I configure Cloudflare to redirect my alternate domain name with HTTPS support? Question

+1
−0

I have several alternate domain names that I would like to redirect to my site:

  • misspelling.example -> example.com
  • longer-domain-with-hyphens.example -> example.com
  • old-brand.example -> example.com

I've tried several redirect services and most don't support HTTPS. If I use them and visit https://misspelling.example/ I get either a security error because of a bad certificate, or they just don't connect at all.

I've heard that Cloudflare offers domain redirects that support HTTPS in their free service tier. Is that true? If so, how do I set it up?

TLS certificates have various fields concerning which domains they apply to. Not all of these are supported by all browsers. Some are obsolete/considered insecure, many client programs have shoddy implementations, and some you have to pay extra for when getting it verified by a CA (if using a paid CA).

Cloudflare essentially acts a MITM attacker on your visitor's TLS connection. They strip out your certificate and inject their own. This will almost certainly be something you need to do through Cloudflare.

In this case you don't even need your own security certificate on your origin server because Cloudflare can do the redirects without an origin server set up at all. I've written an answer with the steps required to set it up.
