By default, Pressable’s origin edge set the `cache-control: max-age` header to **1 year** for static assets.

At this time, it’s not possible to extend the cache duration beyond 1 year or override these headers.

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
```
