[edit]

This provides more fine-grained control over purging of pages cached by an HTTP accelerator such Varnish or Squid. Normally, when the cache is purged, the internal URL is purged ($title->getInternalURL()), as well as the action=history variant of that. This allows a hook listener to change (usually, add to), the list of affected URLs, if additional URLs depend on the content of a title.
