To completely disable caching in your application, ensure every page contains a no-cache directive.
+### Opting Out of Caching from the client-side
+
+The value of the `` element can also be controlled by a client-side API exposed via `Turbo.cache`.
+
+```js
+// Set cache control of current page to `no-cache`
+Turbo.cache.exemptPageFromCache()
+
+// Set cache control of current page to `no-preview`
+Turbo.cache.exemptPageFromPreview()
+```
+
+Both functions will create a `` element in the `` if the element is not already present.
+
+A previously set cache control value can be reset via:
+
+```js
+Turbo.cache.resetCacheControl()
+```
