## Change Cache Reserve setting

`client.Cache.CacheReserve.Edit(ctx, params) (*CacheReserveEditResponse, error)`

**patch** `/zones/{zone_id}/cache/cache_reserve`

Increase cache lifetimes by automatically storing all cacheable files into Cloudflare's persistent object storage buckets. Requires Cache Reserve subscription. Note: using Tiered Cache with Cache Reserve is highly recommended to reduce Reserve operations costs. See the [developer docs](https://developers.cloudflare.com/cache/about/cache-reserve) for more information.

    Body param: Value of the Cache Reserve zone setting.

    - `const CacheReserveEditParamsValueOn CacheReserveEditParamsValue = "on"`

    - `const CacheReserveEditParamsValueOff CacheReserveEditParamsValue = "off"`

### Returns
