Redirect one domain to another

If you have an alias domain that only forwards traffic to another domain, 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.

    TypeNameIPv4 addressProxy status
    A@192.0.2.1Proxied
    Awww192.0.2.1Proxied
  3. Use Redirect rules to forward traffic from your alias domain to your other domain.

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

    Example

    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: Enabled

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

    Request URLTarget URLStatus code
    http://smallshop.example.com/https://globalstore.example.net/301
    http://smallshop.example.com/admin/?logged_out=truehttps://globalstore.example.net/admin/?logged_out=true301
    https://smallshop.example.com/?all_items=1https://globalstore.example.net/?all_items=1301
    http://example.com/about/(unchanged)n/a
