Hostname specific behavior

When you want to customize the behavior for specific custom hostnames, explore the following options:

• For less than 125 hostnames:

  • Page Rules Open external link : Set custom behavior per hostname or path, such as modiying cache behavior or setting higher security levels.
  • Rate Limiting Open external link : Set up rate limiting rules to match custom hostnames on a per-path or per-hostname basis.

• For more than 125 hostnames:

  • Custom metadata : Configure additional settings for custom hostnames using Cloudflare Workers to define per-hostname behavior.
  • Enforce specific protocols: Using a PATCH request Open external link , you can enforce a minimum TLS version and enable TLS 1.3 and HTTP/2.
  • Custom origin servers :

    A custom origin server lets you send traffic from one or more custom hostnames to somewhere besides your default proxy fallback, such as:

    • soap.stores.com goes to origin1.com
    • towel.stores.com goes to origin2.com
