How to Redirect One Domain to Another in Cloudflare

Posted
Bytechie

If you have an alias domain that only forwards traffic to another domain (that is, the domain does not have an associated origin server of its own), you can set up redirects directly within Cloudflare.

  1. Add your alias domain (for example, previous.com) to Cloudflare.
  2. Make sure that your alias domain has a proxied DNS A or CNAME record that properly resolves DNS queries. You may also want to include a record for the www subdomain.

    Use the IP address 192.0.2.1 for the A record. This address does not route traffic to an origin server but allows Cloudflare to apply rules, redirects, and Workers to incoming traffic. The equivalent IP address for an AAAA record is 100::.

    Type Name IPv4 address Proxy status
    A @ 192.0.2.1 Proxied
    A www 192.0.2.1 Proxied

  3. When incoming requests match

    • Field: Hostname
    • Operator: equals
    • Value: smallshop.example.com

    If you are using the Expression Editor, enter the following expression:
    (http.host eq "smallshop.example.com")

    Then

    • Type: Dynamic
    • Expression: concat("https://globalstore.example.net", http.request.uri.path)
    • Status code: 301
    • Preserve query string: EnabledUse Redirect rules to forward traffic from your alias domain to your other domain.

      This example single redirect will redirect all requests for smallshop.example.com to a different hostname using HTTPS, keeping the original path and query string.

For example, the redirect rule would perform the following redirects:

Request URL Target URL Status code
http://smallshop.example.com/ https://globalstore.example.net/ 301
http://smallshop.example.com/admin/?logged_out=true https://globalstore.example.net/admin/?logged_out=true 301
https://smallshop.example.com/?all_items=1 https://globalstore.example.net/?all_items=1 301
http://example.com/about/ (unchanged) n/a
