Boost is one of the most widely used Drupal modules designed for static page caching. It creates html files for Drupal pages.When an anonymous user visits the page for the first time, boost generates an html page and then serves the html directly to the other anonymous users of the site, till the page cache expires, which increases the performance of the site for anonymous users, as everything is handled at the Apache level. Nevertheless, there will be situations where boost might not cache a page. Read on to know if you have faced a similar problem.
