How to add a rule: basic settings
Use Rules to set up custom settings for certain file types or paths.
1. In the resource settings, go to the Rules tab, click the Action button and choose Add rule.
2. Specify a rule name.
2. Select the Match Type:
- For Regular expression specify the path or file types by a regular expression, starting with '^/' or '/'.
- For Regular expression (legacy) specify the path or file types by a regular expression.
Important! When this match type is selected, "/" is automatically added to the beginning of a regular expression. This type will be removed soon.
Rules settings are equal to the Resource Settings, you can specify additional settings for the rule in the Options section.
How Rules interact with the resource settings
1. If an option isn't added in Rule, the value is inherited from the resource settings.
For example, if you do not add options in the Rule for caching settings, the caching settings for content set in the rule will be inherited from the resource settings:
2. If the option is added to Rule and disabled, you disable this option for the Rule.
For example, in the resource settings access to the content is restricted from Russia, and in Rule Country Access Policy slider is on the left and the option is grey. Then, no country restrictions will be applied to the content specified in the Rule.
3. If the option is added to the Rule and has its own value, to the Rule content will applied value you set up in Rule.
For example, in the resource settings Browser Caching is 4 days and in the Rule is 30 minutes, content specified in Rules will be cached for 30 minutes and all the other content for 4 days.

1. In the resource settings, go to the Rules tab and click the arrow next to the Add rule button.
2. Select the desired template: added by account users or a system template.
