Set up redirects

Often, you might want to set up redirects within Cloudflare.

Redirect a subdomain to apex domain

Sometimes, you might want all traffic to a subdomain (www.example.com) to actually go to your apex domain (example.com).

1. Create a proxied DNS A record for your subdomain. This record can point to any IP address since all traffic will be redirected prior to reaching the address.

   Type	Name	IPv4 address	Proxy status
   A	www	192.0.2.1	Proxied

2. Create a Single Redirect to forward traffic from your subdomain to your apex domain.

When incoming requests match

Using the Expression Editor:
(http.request.full_uri contains "www.example.com")

Then

• Type: Dynamic
• Expression: concat("https://","example.com",http.request.uri.path)
• Status code: 301

Redirect apex domain to a subdomain

Sometimes, you might want all traffic to your apex domain (example.com) to actually go to a subdomain (www.example.com).

1. If you have already added that subdomain at your host, create a corresponding DNS A or CNAME record for that subdomain.

2. Create a proxied DNS A record for your apex domain. This record can point to any IP address since all traffic will be redirected prior to reaching the address.

   Type	Name	IPv4 address	Proxy status
   A	@	192.0.2.1	Proxied

3. Create a Single Redirect to forward traffic from your apex domain to your subdomain.

When incoming requests match

Using the Expression Editor:
(lower(http.host) eq "example.com")

Then

• Type: Dynamic
• Expression: concat("https://","www.example.com",http.request.uri.path)
• Status code: 301
