Cache Refresher

This is a WordPress plugin that allows you to refresh your cache periodically or on-demand.

And by refreshing, I mean it will ping your page using a HTTP GET request.

It's mostly useful when used in conjunction with microcaching or for warming your cache after a deployment.

The plugin works in the background using a queue so it will refresh one page at the time and thus will hopefully avoid overloading your server.

On demand

This allows you to refresh every page on your site. There are two methods you can use

HTTP request

You can refresh every page on your site by sending a GET request to an URL. You can find this URL under Options and Cache Refresher. It looks something like this:

https://example.com/wp-json/cache-refresher/v1/refresh-all?token=gnjvb5th13ken07nmwov9gqnt

You can ping it using your CI pipeline or something. I may add a button to the UI to do this also.

WP CLI

Run the following command

wp cache-refresher refresh-all

Scheduled refreshing

This plugin will refresh all pages on your site every day at 00:01 in the site time zone. I will maybe add some option to disable or customize this in the future.

Refresh on save

When you save or delete a post, the plugin will ping the permalink of that post. I will maybe add some option to disable or customize this in the future.

⚠️ Refresh on save doesn't use a queue. Instead it's done immediately after the save using an asynchronous request
