API Cache Pro

This plugin enables caching for the WordPress REST API to improve performance. Once enabled you can modify the basic settings via the Customizer.

Customizer Options:

• Disable Cache (Default: Disabled)

• Set Default Cache Timeout (Default: 300)

Request Headers

Several Headers are added to all the API Requests. This plugin will also modify the Cache-Control header as well. Here is an example of the available custom headers.

X-API-CACHE-PRO: Cached X-API-CACHE-PRO-EXPIRES: January 20, 2019, 12:39 AM UTC X-API-CACHE-PRO-EXPIRES-DIFF: 5 mins X-API-CACHE-PRO-KEY: api_cache_pro_78be25416f69cd3a885dcf14017a0691

• X-API-CACHE-PRO – Displays Cached, or Not Cached.

• X-API-CACHE-PRO-EXPIRES – Displays the date/time the cache is set to expire.

• X-API-CACHE-PRO-EXPIRES-DIFF – Displays the difference from current time to the time cache is set to expire.

• X-API-CACHE-PRO-KEY – Displays the key used for the cache.

This plugin offers several filters so you can disable these headers:

You can use these filters to disable any of the headers. Here is an example to disable the Key Header.

/** * Disable API Cache Pro Key Header. * * @access public */ function disable_api_cache_pro_key_header() { return false; } add_action( 'api_cache_pro_key_header', 'disable_api_cache_pro_key_header' );

Clearing Cache

The cache will automatically get cleared if you do any of the following:

• Disable the Cache

• Update the Default Cache Timeout Length

• Update any post, page or custom post type.

• Deactivate or Uninstall the plugin

You can skip that cache by adding the following param to any request:

`cache=disabled<pre><h3>WP-CLI Support</h3>
