- Cloudflare lets you add many domains and each will get their own free tier of service. Here is a screenshot of my Cloudflare account. Each of those domains is an alternate domain that has been configured to redirect:
- 
- After you add your domain to Cloudflare, you need to go into the DNS Records for that domain.
- - Cloudflare will tell you two `NS` records. You need to log into your domain registrar and set these two values as the `NS` records for your domain within your domain registrar. This will establish Cloudflare as our DNS host for that domain.
- - In Cloudflare, you need to add two `A` records for domain, one for the domain apex (no subdomain) and the other for the wildcard subdomain (`*`). The IP address you set for the origin server doesn't matter much, because Cloudflare itself will handle all requests for this domain. I use `1.1.1.1`. Both records need to be set as "Proxied" which sets them up to be served by Cloudflare's web servers.
- 
- Then you need to edit the "Page Rules" for the domain in Cloudflare. Create a rule to redirect `*alternate-domain.example/*` to `https://$1main-domain.example$2` or `https://main-domain.example/$2`. `$1` and `$2 are variables that correspond to the first and second wildcards (*) respectively. The variant with `$1` will preserve the subdomain with the redirect, and the version without the `$1` will remove the subdomain.
- 
- It may take a few hours for everything to settle:
- - The `NS` records for your alternate domain need to propagate.
- Cloudflare needs to validate that you have changes your `NS` records to point to them.- - Cloudflare needs to create a TLS security certificate for your domain so that HTTPS traffic works.
- All of those things should happen automatically. After a little while you should be able to visit `http://alternate-domain.example/` and `https://alternate-domain.example/` to get redirected to your main domain.
