+description: Browser cache control plugin configuration reference
+---
+## Function Description
+The `cache-control` plugin implements adding `Expires` and `Cache-Control` headers to the response based on the URL file extensions, making it easier for the browser to cache files with specific extensions, such as `jpg`, `png`, and other image files.
+
+## Runtime Attributes
+Plugin execution phase: `Authentication Phase`  
+Plugin execution priority: `420`
+
+## Configuration Fields
+| Name      | Data Type   | Requirements                                                                                                | Default Value | Description                       |
+|-----------|-------------|----------------------------------------------------------------------------------------------------------|---------------|-----------------------------------|
+| suffix    | string      | Optional, indicates the file extensions to match, such as `jpg`, `png`, etc.<br/>If multiple extensions are needed, separate them with `\|`, for example `png\|jpg`.<br/>If not specified, it matches all extensions. | -             | Configures the request file extensions to match            |
+| expires   | string      | Required, indicates the maximum caching time.<br/>When the input string is a number, the unit is seconds; for example, if you want to cache for 1 hour, enter 3600.<br/>You can also enter epoch or max<br/>, with the same semantics as in nginx. | -             | Configures the maximum caching time                |
+
+## Configuration Example
+1. Cache files with extensions `jpg`, `png`, `jpeg`, with a caching time of one hour
+```yaml
+suffix: jpg|png|jpeg
+expires: 3600
+```
+With this configuration, the following requests will have `Expires` and `Cache-Control` fields added to the response headers, with an expiration time of 1 hour later.
+```bash
+curl http://example.com/test.png
+curl http://example.com/test.jpg
+```
+2. Cache all files, with a maximum caching time of `"Thu, 31 Dec 2037 23:55:55 GMT"`
+```yaml
+expires: max
+```
