By default, Pressable’s CDN will set the `cache-control: max-age` to 7 days — unless the asset has a parameter, in which case it will be 10 years. If you’d like to increase this amount of time, you may do so by appending *any* parameter to your static assets.

That parameter will increase the time the asset remains cached from 7 days to 10 years.

The [Pressable Cache Management plugin](https://pressable-staging.mystagingwebsite.com/knowledgebase/pressable-cache-management-plugin/#cdn-controls) includes functionality to automatically do this for all `jpeg`, `jpg`, `gif`, `png`, `bmp`, `ico`, `js` and `css` files.

You can verify that the `cache-control` headers have changed by running the following curl commands for the static asset(s) in question:

```
$ curl -sI https://149345589.v2.pressablecdn.com/wp-content/uploads/2018/08/logo-new-4x-compressed.png | grep ^cache-controlcache-control: max-age=604800
```

```
$ curl -sI https://149345589.v2.pressablecdn.com/wp-content/uploads/2018/08/logo-new-4x-compressed.png?expires | grep ^cache-controlcache-control: max-age=315360000
```
