Cache

Fun fact. Drupal was started in 2001 — two years before WordPress was released. According to W3Techs, this CMS powers 1.1% of all websites, from blogs to e-commerce and government sites, holding a 1.6% market share.

When it comes to speed optimization techniques, the use of HTTP caching is a very important one that every developer knows about. Little but very important caching “assistants” are HTTP headers. Today, we will discuss the role of HTTP caching in speed improvement, what HTTP headers are, and take a special tour of cache-related HTTP response headers.

Drupal is a free open source solution, which predetermined its development. Like other similar CMS, it has a developed user community, which creates modules, patches, and thematic assemblies based on the core. Exist thousands of articles describing how secure and flexible Drupal is.  The core of the system itself provides few content management tools. This is not the mistake of the creators, but a conscious decision that emphasizes the flexibility of the system and its focus on experienced developers - or those, who are willing to learn, read forums and watch video manuals. But even in this minimal set of tools, some parts are very useful for the future site - for example, pre-installed tools for organizing user accounts. They help develop large portals with forums and other social ways visitors interact.
