Cache Rule

Overview

Cache rules cache matching requests. When a request hits a rule, the cached content is returned directly, reducing backend load and speeding up access. Different rule types suit different scenarios.

Prerequisites

Cache rules require the Cache feature to be enabled on the target website first: open the website edit page, turn Cache on, and choose a cache location (memory / file / all). Only then do cache rules take effect.

Steps

1. Click New at the top-left.
2. In the dialog, choose the Website and enter a Rule Name.
3. Select a Rule Type (Suffix Match / Specific Directory / Specific File) and fill in the matching Rule Content for that type.
4. Choose a Param Type (Ignore Parameters / Full Parameters).
5. Set the Cache Time, Priority, and Request Method, and add Remarks if needed.
6. Click Confirm to save.

To modify or remove a rule, use Edit or Delete in the list action column.
