# Configuration Rules

Configuration Rules allow you to customize certain Cloudflare [configuration settings](https://developers.cloudflare.com/rules/configuration-rules/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](https://developers.cloudflare.com/ruleset-engine/rules-language/expressions/) and [Edit expressions in the dashboard](https://developers.cloudflare.com/ruleset-engine/rules-language/expressions/edit-expressions/).

Note

Configuration Rules require that you [proxy the DNS records](https://developers.cloudflare.com/dns/proxy-status/) of your domain (or subdomain) through Cloudflare.

## Rules templates

Cloudflare provides you with rules templates for common use cases.

1. In the Cloudflare dashboard, go to the Rules **Overview** page.  
[ Go to **Overview** ](https://dash.cloudflare.com/?to=/:account/:zone/rules/overview)
2. Select **Templates**, and then select one of the available templates.

You can also refer to the [Examples gallery](https://developers.cloudflare.com/rules/examples/) 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         | 300 |

## Execution order

The execution order of Rules features is the following:

* [Single Redirects](https://developers.cloudflare.com/rules/url-forwarding/single-redirects/)
* [URL Rewrite Rules](https://developers.cloudflare.com/rules/transform/url-rewrite/)
* [Configuration Rules](https://developers.cloudflare.com/rules/configuration-rules/)
* [Origin Rules](https://developers.cloudflare.com/rules/origin-rules/)
* [Bulk Redirects](https://developers.cloudflare.com/rules/url-forwarding/bulk-redirects/)
* [Managed Transforms](https://developers.cloudflare.com/rules/transform/managed-transforms/)
* [Request Header Transform Rules](https://developers.cloudflare.com/rules/transform/request-header-modification/)
* [Cache Rules](https://developers.cloudflare.com/cache/how-to/cache-rules/)
* [Snippets](https://developers.cloudflare.com/rules/snippets/)
* [Cloud Connector](https://developers.cloudflare.com/rules/cloud-connector/)

The different types of rules listed above will take precedence over [Page Rules](https://developers.cloudflare.com/rules/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](https://developers.cloudflare.com/ruleset-engine/rules-language/actions/) the last change made by rules in the same [phase](https://developers.cloudflare.com/ruleset-engine/about/phases/) 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](https://developers.cloudflare.com/ruleset-engine/reference/phases-list/) for the product execution order.

Warning

Using Cloudflare challenges along with Rules features may cause challenge loops. Refer to [Rules troubleshooting](https://developers.cloudflare.com/rules/reference/troubleshooting/) for more information.

## Troubleshooting

When troubleshooting Configuration Rules, use [Cloudflare Trace](https://developers.cloudflare.com/rules/trace-request/) to determine if a rule is triggering for a specific URL.
