[NOTE: This module has been deprecated as of June 2013 in favor of Cache Expiration. If you're currently using Boost Expire, please follow these directions to switch from Boost Expire to Cache Expiration on your site!]
A cache expiration module to go with Boost for Drupal 7.
Currently, Boost for Drupal 7 doesn't do any active cache expiration (see #1069438: How to Flush Boost Cache in Drupal 7.x), and this means that when you update a node, post a comment, etc., Boost will continue serving stale content from its static HTML cache until the file is finally cleaned up on a cron run.
For many sites, especially smaller sites where content is updated infrequently and cron may be run hourly or even less frequently, this means stale content will be served for quite some time, unless someone visits the Performance page and clears all the site's caches manually.
This module alleviates that problem by simply flushing Boost's static HTML cache every time a node or comment is posted or updated. You can set the module to respect your site's Minimum cache lifetime so it doesn't flush the cache until the minimum lifetime has passed.
This module may become deprecated in favor of a more universal solution (like Boost integration with the Cache Expiration module).
