設定ルール
設定ルールを使用すると、受信リクエストに対して特定のCloudflare 設定をカスタマイズできます。
設定ルールの式は、ルール設定が適用されるリクエストを決定します。式に関する詳細は、式およびダッシュボードでの式の編集を参照してください。
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.
利用可能な設定ルールの数は、Cloudflareプランによって異なります：
| Free | Pro | Business | Enterprise | |
|---|---|---|---|---|
Availability | Yes | Yes | Yes | Yes |
Number of rules | 10 | 25 | 50 | 125 |
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.
When troubleshooting 設定ルール, use Cloudflare Trace to determine if a rule is triggering for a specific URL.
