Redirect root domain to www using CloudFlare
Setup a redirect using CloudFlare to redirect requests from the root domain to the www subdomain.
Login to your CloudFlare account and select the domain you want to apply the redirect rule to. The free-tier plan is sufficient for this setup and allow us to setup 10 rules for free.
Goto “Rules” -> “Redirect rules” and create a new rule using the following settings:
- Rule name: Redirect root to www
- When incoming requests match: Custom filter expression
- Field: Hostname
- Operator: equals
- Value: domain.com
Expression preview:
(http.host eq "domain.com")- Then
- Type: Dynamic
- Expression:
concat("https://www.domain.com", http.request.uri.path) - Status code: 301
- Preserve query string: Checked
Important
For the CloudFlare redirect rules to work you have to make sure that the DNS records for the root domain is proxied through CloudFlare. This is indicated by the orange cloud icon in the DNS records.
