Configuration Rules
Configuration Rules allow you to customize certain Cloudflare configuration settings for matching incoming requests.
The configuration rule expression will determine to which requests the rule settings will apply. For more information on expressions, refer to Expressions and Edit expressions in the dashboard.
Rules templates
Cloudflare provides you with rules templates for common use cases. In the dashboard, go to your zone > Rules > Templates and select one of the available templates. You can also refer to the Examples gallery in the developer docs.
Availability
The number of available configuration rules varies according to your Cloudflare plan:
| Free | Pro | Business | Enterprise | |
|---|---|---|---|---|
Availability | Yes | Yes | Yes | Yes |
Number of rules | 10 | 25 | 50 | 125 |
Execution order
The execution order of Rules features is the following:
The different types of rules listed above will take precedence over Page Rules. This means that Page Rules will be overridden if there is a match for both Page Rules and the Rules products listed above.
Generally speaking, for non-terminating actions the last change made by rules in the same phase will win (later rules can overwrite changes done by previous rules). However, for terminating actions (Block, Redirect, or one of the challenge actions), rule evaluation will stop and the action will be executed immediately.
For example, if multiple rules with the Redirect action match, Cloudflare will always use the URL redirect of the first rule that matches. Also, if you configure URL redirects using different Cloudflare products (Single Redirects and Bulk Redirects), the product executed first will apply, if there is a rule match (in this case, Single Redirects). Refer to the Phases list for the product execution order.
Troubleshooting
When troubleshooting configuration rules, use Cloudflare Trace to determine if a rule is triggering for a specific URL.
