Page Rules trigger certain actions whenever a request matches one of the URL patterns you define. Learn to create and edit page rules and understand the different settings available.
Overview
You can define a page rule to trigger one or more actions whenever a certain URL pattern is matched. Page Rules are available in the Rules app, in the Page Rules tab.
The default number of allowed page rules depends on the domain plan as shown below.
| Plan | Page rules allowed |
|
Free |
3 |
|
Pro |
20 |
|
Business |
50 |
|
Enterprise |
125 |
You can purchase additional rules (up to a maximum of 100) for domains in the Free, Pro, and Business plans.
Before getting started
It is important to understand two basic Page Rules behaviors:
- Only the highest priority matching page rule takes effect on a request.
- Page rules are prioritized in descending order in the Cloudflare dashboard, with the highest priority rule at the top.
A page rule matches a URL pattern based on the following format (comprised of four segments): <scheme>://<hostname><:port>/<path> An example URL with these four segments looks like:
https://www.example.com:443/image.png
The scheme and port segments are optional. If omitted, scheme matches both http:// and https:// protocols. If no port is specified, the rule will match all ports.
Finally, you can disable a page rule at any time. While a rule is disabled, actions won’t trigger, but the rule still appears in the Rules app in the Page Rules tab, is editable, and counts against the number of rules allowed for your domain. The Save as Draft option creates a page rule that is disabled by default.
Create a page rule
The steps to create a page rule are:
- Log in to the Cloudflare dashboard.
- Select the domain where you want to add the page rule.
- Click the Rules app.
- In the Page Rules tab, click Create Page Rule. The Create Page Rule for <your domain> dialog opens.
- Under If the URL matches, enter the URL or URL pattern that should match the rule. Learn more about wildcard matching
- Next, under Then the settings are: click + Add a Setting and select the desired setting from the dropdown. You can include more than one setting per rule. Learn more about settings in the summary below.
- In the Order dropdown, specify the desired order: First, Last or Custom.
- To save, click one of the following options:
- Save as Draft to save the rule and leave it disabled.
- Save and Deploy to save the rule and enable it immediately.
Edit a page rule
To modify an existing rule:
- Log in to the Cloudflare dashboard.
- Select the domain where you want to edit your page rule.
- Click the Rules app.
- In the Page Rules tab, locate the rule to edit.
- Proceed to make the necessary changes, as follows:
- To enable or disable a rule, click the On/Off toggle.
- To modify the URL pattern, settings, and order, click the Edit button (wrench icon). In the dialog, enter the information you’d like to change.
- To remove a rule, click the Delete button (x icon) and confirm by clicking OK in the Confirm dialog.
Understand wildcard matching and referencing
You can use the asterisk (*) in any URL segment to match certain patterns. For example,
example.com/t*stWould match:
example.com/test example.com/toast example.com/trust
example.com/foo/* does not match example.com/foo. However, example.com/foo* does.
Helpful tips
- 要同时匹配 http 和 https，只需写入 example.com 即可。无需写入 *example.com。
- To match every page on a domain, write example.com/*. Just writing example.com won’t work.
- To match every page on a domain and it's subdomains, write *.example.com/*. Just writing example.com won’t work.
Referencing wildcard matches
You can reference a matched wildcard later using the $X syntax. X indicates the index of a glob pattern. As such, $1 represents the first wildcard match, $2 the second wildcard match, and so on.
This is specifically useful with the Forwarding URL setting. For example:
You could forward:
http://*.example.com/*to:
http://example.com/images/$1/$2.jpgThis rule would match:
http://cloud.example.com/flare.jpgwhich ends up being forwarded to:
http://example.com/images/cloud/flare.jpgTo use a literal $ character in the forwarding URL, escape it by adding a backslash (\) in front: \$.
Summary of Page Rules Settings
Settings control the action Cloudflare takes once a request matches the URL pattern defined in a page rule. You can use settings to enable and disable multiple Cloudflare features across several of the dashboard apps. Note that:
- Some settings require a Pro, Business or Enterprise domain plan.
- You can specify more than one setting to apply when the rule triggers.
- Ports 80, 443, and 8080 are the only ports where Cloudflare Caching is available.
Below is the full list of settings available, presented in the order that they appear in the Cloudflare Page Rules UI.
|
Setting |
Description |
Plans |
|
Always Online |
Turn on or off the Always Online feature of the Cloudflare Caching app. Learn more. Disable this for sections of your site that should never return cached data, such as APIs or payment/cart pages. |
|
|
Always Use HTTPS |
Turn on or off the Always Use HTTPS feature of the Edge Certificates tab in the Cloudflare SSL/TLS app. If enabled, any http:// URL is converted to https:// through a 301 redirect. If this option does not appear, you do not have an active Edge Certificate. |
|
|
Auto Minify |
Indicate which file extensions to minify automatically. Learn more. |
|
|
Automatic HTTPS Rewrites |
Turn on or off the Cloudflare Automatic HTTPS Rewrites feature of the Edge Certificates tab in Cloudflare SSL/TLS app. Learn more. |
|
|
Browser Cache TTL |
Control how long resources cached by client browsers remain valid. The Cloudflare UI and API both prohibit setting Browser Cache TTL to 0 for non-Enterprise domains. Learn more. |
|
|
Browser Integrity Check |
Inspect the visitor's browser for headers commonly associated with spammers and certain bots. Learn more. |
|
|
Bypass Cache on Cookie |
Bypass Cache and fetch resources from the origin server if a regular expression matches against a cookie name present in the request. 如果您将这个设置和 Cache On Cookie 设置都添加到同一 Page Rule 中，则 Cache On Cookie 的优先级将高于 Bypass Cache on Cookie。 See Additional details below to learn about limited regular expression support. |
|
|
Cache By Device Type |
Separate cached content based on the visitor’s device type. Learn more. |
|
|
Cache Deception Armor |
Protect from web cache deception attacks while still allowing static assets to be cached. This setting verifies that the URL's extension matches the returned Content-Type. Learn more. |
|
|
Cache Key |
Also referred to as Custom Cache Key. Control specifically what variables to include when deciding which resources to cache. This allows customers to determine what to cache based on something other than just the URL. Learn more. |
|
|
Cache Level |
Apply custom caching based on the option selected: No Query String - Delivers resources from cache when there is no query string. Ignore Query String - Delivers the same resource to everyone independent of the query string. Standard - Caches all static content that has a query string. Cache Everything - Treats all content as static and caches all file types beyond the Cloudflare default cached content. Respects cache headers from the origin web server unless Edge Cache TTL is also set in the Page Rule. When combined with an Edge Cache TTL > 0, Cache Everything removes cookies from the origin web server response. |
|
|
Cache on Cookie |
Apply the Cache Everything option (Cache Level setting) based on a regular expression match against a cookie name. If you add both this setting and Bypass Cache on Cookie to the same page rule, Cache On Cookie takes precedence over Bypass Cache on Cookie. |

Additional details
Bypass Cache on Cookie setting
This setting is available to business and enterprise customers.
The Bypass Cache on Cookie setting supports basic regular expressions (regex) as follows:
- A pipe operator (represented by |) to match multiple cookies using OR boolean logic. For example, bypass=.*|PHPSESSID=.* would bypass the cache if either a cookie called bypass or PHPSESSID were set, regardless of the cookie's value.
- The wildcard operator (represented by .*), such that a rule value of “t.*st=” would match both a cookie called test and one called teeest.
Limitations include:
- 150 chars per cookie regex
- 12 wildcards per cookie regex
- 1 wildcard in between each | in the cookie regex
To learn how to configure Bypass Cache on Cookie with a variety of platforms, review these articles:
- Caching Anonymous Page Views with WordPress or WooCommerce
- Caching Anonymous Page Views with Magento 1 and Magento 2
- How do I cache static HTML?
Note: If you add both this setting and the enterprise-only Cache On Cookie setting to the same page rule, Cache On Cookie takes precedence over Bypass Cache on Cookie.
