API Cache Pro

Description

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:

Filter
Type
Default

api_cache_pro_header
boolean
true

api_cache_pro_key_header
boolean
true

api_cache_pro_expires_header
boolean
true

api_cache_pro_expires_diff_header

api_cache_pro_control_header
boolean
true

api_cache_pro_max_age
integer
Default Timeout or 300 (5 Minutes)

api_cache_pro_s_max_age
integer
Default Timeout or 300 (5 Minutes)

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:
