The caching control panel

After installation, you will find a Caching control panel in Plone’s site setup. This consists of four main tabs:

  • Change settings, where you can control caching behaviour

  • Import settings, where you can import pre-defined profiles of cache settings

  • Purge caching proxy, where you can manually purge content from a caching proxy. This tab only appears if you have purging enabled under Change settings.

  • RAM cache, where you can view statistics about and purge the RAM cache.

Under the settings tab, you will find four fieldsets:

  • General settings, for global options such as turning caching on or off.

  • Caching proxies, where you can control Plone’s use of a caching proxy such as Squid or Varnish.

  • Caching operation mappings, where caching rulesets (hints about views and resources used for caching purposes) can be associated with caching operations (which either intercept a request to return a cached response, or modifies a response to add cache control headers). This is also where rulesets for legacy page templates (created through the web or the portal_skins tool) are configured.

  • Detailed settings, where you can configure parameters for individual caching operations.
