Purge Cache Warmer


This module places updated versions of content that have been invalidated, into internal and external caches (a process known as cache warming).


As requests are made to the site, the URL Queuer module maintains a table mapping cache tags for the pages to URLs. Once content edits/updates trigger Drupal core's internal cache invalidation, the invalidations are registered by the URL queuer module. Url Queuer then triggers external invalidations by URL for purgers that support it.

Random user auth. DANGEROUS!

This module provides auto-authenticate-random-user.

If user does not have a valid session, one is created with a random user.
This is VERY DANGEROUS and should NEVER be enabled on public
available environments.

Use this module for performance testing for intranets and other
personalized websites.


  • Random user select during hook_boot()
  • Admin user is omitted
  • Redirect to requested page

Resource Hints

This module provides facilities for user agent resource hints.

Please see https://www.w3.org/TR/resource-hints/ for more details.

Current Functionality:

Cache Mover

Cache Mover is a cache backend useful for migrating cache bins from one backend to another with minimal or no performance loss and without any downtime.


Imagine you have a cache bin stored using a particular backend, such as DrupalDatabaseCache (Drupal's default). Later, you want to switch from that backend to another backend such as Redis, which is dedicated and faster.

Query Cache

Query Cache allows to automatically cache all queries in memcache / redis / lcache.
