This documentation describes the latest stable D7 version of the Flickr Cache Warmer sub-module.

Rebuilds the page cache after cron runs for selected content types also known as cache warming. It avoids long page loads for the first visitor after a cron run. Feel free to use any method of cache warming suggested (this sub-module, your own script or the Cache Warmer module) but don't use them together.

The server virtually visits all nodes of selected content types to ensure the cache of these pages is rebuild after a cron run to avoid long page loads for a real visitor. It can be limited to selected content types at admin/config/media/flickr. The connection method automatically falls back to cURL if stream_socket_client fails or is not available. Note that it uses the HEAD method where the server MUST NOT return a message-body in the response. Drupal will rebuild the full page's cache anyway.

Set the 'Minimum cache lifetime' to 'none' at admin/config/development/performance.

It is recommended to set the cron interval to something sensible. By default it is set to 3 hours at admin/config/system/cron. For many cases 'once a day' or even 'once a week' is more than enough. New or edited content will refresh anyway after hitting the 'Save' button.
