+| Name          | Scope    | Description      | Example                     | Type      |

+#### Video Caching
+
+Note that the Adklip adapter expects a client-side Prebid Cache to be enabled for video bidding.
+
+```js
+pbjs.setConfig({
+    cache: {
+        url: 'https://prebid.adnxs.com/pbc/v1/cache'
+    }
+});
+```
