How to enable the Redis object cache

The Redis section in Enhance describes Redis as a persistent object cache. If your application supports it, Redis can cache the results of complex database queries. The panel states that the Redis service starts within the website’s PHP container.

Enable Redis on the server

1. Open your website in the Enhance control panel.
2. In the website’s top menu, choose Advanced → Developer tools.
3. Click Redis in the page’s left section navigation.
4. Read the description beside the switch, including the requirement that your application supports Redis.
5. Turn the Redis switch on. Check the resulting switch state and any message displayed by the panel.

The screenshot below shows the Redis section with the switch off.
