详情介绍:

Purgely manages caching behavior for WordPress sites using Fastly as an edge caching solution. The plugin exposes useful APIs to help control how pages on your site are cached, as well as provides sane defaults to make this a plug and play solution for Fastly cache management. The plugin handles the following: Each of these items have sane defaults with ways to override them and configure them to your liking. Additionally, the plugin exposes a WP CLI command to provide more flexible purging options.

安装:

手动安装
  1. Upload the plugin directory to /wp-content/plugins/
  2. 通过WordPress的的“Plugins”菜单激活插件
WP CLI installation
  1. Run wp plugin install --activate purgely
配置 Purgely provides a number of constants that can be used to control the behavior of the plugin and Fastly's cache. Users who wish to change these values should define the constants in wp-config.php. After installing, you should define PURGELY_FASTLY_KEY and PURGELY_FASTLY_SERVICE_ID in wp-config.php. The plugin will work without them; however, you will not be able to purge by surrogate key or purge all without configuring these options. To define them copy the following code to your wp-config.php file, update the key to use your key, and the service ID to match the fastly service you're using: define( 'PURGELY_FASTLY_KEY', '39c4820390d8f050giweda50268c7583' ); define( 'PURGELY_FASTLY_SERVICE_ID', 'abcdefghijklmn1234567890' ); Configuring other constants is similarly done by defining the constant in wp-config.php. All constants are explained below. PURGELY_API_ENDPOINT Defines the API endpoint for Fastly. This should not usually need to be changed, but is added in the event that Fastly decides to use a different API endpoint, or if there is a need for a user to have a special endpoint. default: (string) '' PURGELY_ALLOW_PURGE_ALL Determines whether or not the plugin can issue a purge all request. Purge all can have dire consequences for a website. As such, this behavior is disabled by default. If can be turned on by setting this value to true. default: (bool) false PURGELY_ENABLE_STALE_WHILE_REVALIDATE Determines whether or not the plugin sets the stale-while-revalidate directive for the Cache-Control header. Setting this value to false will turn off the stale-while-revalidate behavior. Note that you can manually control this behavior via the functions exposed in the plugin regardless of this configuration option. This option only controls the default plugin behavior. default: (bool) true PURGELY_STALE_WHILE_REVALIDATE_TTL Sets the TTL for the stale-while-revalidate directive in seconds. The value instructs Fastly to continue serving stale content while new content is generated for the duration of the value that is set. default: (int) 86400 PURGELY_ENABLE_STALE_IF_ERROR Determines whether or not the plugin sets the stale-if-error directive for the Cache-Control header. Setting this value to false will turn off the stale-if-error behavior. Note that you can manually control this behavior via the functions exposed in the plugin regardless of this configuration option. This option only controls the default plugin behavior. default: (bool) true PURGELY_STALE_IF_ERROR_TTL Sets the TTL for the stale-if-error directive in seconds. The value instructs Fastly to continue serving stale content while the origin site is serving an error for the duration of the value that is set. default: (int) 86400 PURGELY_SURROGATE_CONTROL_TTL Sets the TTL for the Surrogate-Control header in seconds. This value is the default TTL for all pages on your site, unless it is cached within the app. Changing this value changes the value for the whole site. default: (int) 300
