Package: plone.app.caching
plone.app.cachingIntroductionThis package provides a Plone UI and default rules for managing HTTP response caching in Plone.
It builds onz3c.caching,plone.cachingandplone.cachepurging.CompatibilityVersionPlone3.x6.0 or above2.x5.21.x5.1, 5.0, 4.3, 4.2, 4.1Installationplone.app.cachingis shipped as a dependency of thePlonepackage, and it should be available on all Plone installations, but
Caching isnot enabled by default, although it is highly recommended to configure caching for every new Plone site.After creating a new Plone site, go toSite Setup, thenAddonsand installHTTP caching support.Under the Advanced header, look for the Caching control panel -- currently only supported on the Classic UI.TroubleshootingWhen the Caching control panel is not there, there can be various reasons for this:If your installation does not load thePlonepackage, but onlyProducts.CMFPlone, thenplone.app.cachingis not included.If the packageisincluded, but you add a Plone Site using the advanced form and disable caching, then the control panel is not there.If you want to install it in an existing Plone Site:Make sure the package is available in the Plone instance, by addingplone.app.cachingorPloneto your installation.From the Plone Site Setup go to the ZMI (Zope Management Interface).Go toportal_setup, and then to the Import tab.Select the HTTP caching support profile, perhaps easiest by id:profile-plone.app.caching:default.Click 'Import all steps'.Source CodeContributors, please read the documentProcess for Plone core's developmentSources are at thePlone code repository hosted at Github.This project is supported byLicenseThe project is licensed under GPLv2.Changelog3.1.4 (2024-02-12)Bug fixes:Fix purging of image scale paths for Dexterity content.

cached in RAMCache instead of not caching anything.

response.status is not set when IPubBeforeAbort is notified.
Fixed by using error_status stored on request by plone.transformchain.

and its scales gets purged.
[stefan, hannosch]Associatedfile_view,image_viewandimage_view_fullscreenby default

handling.

[stefan, hannosch]Fix documentation to refer to the correctresourceRegistriesinstead of
the singular version.
