Redis Object Cache plugin in WordPress

How to set up the Redis Object Cache plugin in WordPress on your Simply.com host

Redis Object Cache plugin uses Redis for caching, which can provide better performance, especially on larger and heavy websites with a lot of cached data accessed on every page load. Since Redis is not available for all customers and requires individual configuration, it must be set up manually.

Step‑by‑step guide to setting up Redis Cache in WordPress

1. Find your Redis details

You can find your Redis details in Our Control Panel in the left‑hand menu under Redis. This is also where you can create a Redis instance if you haven’t done so already.

Replace <port>, <hostnavn> and <password> with the relevant details for your Redis instance.
