Details
Enable/disable page view caching. Cdn configuration causes the following changes in behaviour:
- The
Cache-Controlheader is changed to allow the cache proxy to blindly cache content for a predetermined period of time (configured by $wgCdnMaxAge). - The
Last-Modifiedheader is artificially shortened to ensure the cache proxy will not renew outdated HTML beyond a certain age. TheLast-Modifieddate will never be older than $wgCdnMaxAge. This will allow to refresh the cached copy in case there were changes to footer icons, sidebar, skin update, and other configuration or skin-level changes not tracked by the wiki page itself. - Purges are sent to ensure content edited by users remains up to date immediately.
The list of Cdn servers to be purged on update must be stored in $wgCdnServers.
Sending purge requests requires the sockets PHP extension.
