Internet is omnipotent these days but what is more important than website is the web application. Most of the business users as well as a large number of common users are usually on portable or mobile devices and they don’t always have an access to a network. With HTML5’s Application Cache, you can provide them with all or some of the functionality they would have online, no matter where they go. To undertake the process of building a cache with HTML5 for offline access, first of all, requires using a cache manifest file. This is quite simple!
One of the easiest ways to improve your application’s performance is by putting a caching solution in front of your database. In this tutorial, I’ll show you how to use Memcached with Rails, Django, or Drupal.
Memcached is an excellent choice for this problem, given its solid history, simple installation, and active community. It is used by companies big and small, and includes giants, such as Facebook, YouTube, and Twitter. The Memcached site, itself, does a good job of describing Memcached as a “Free & open source, high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.”
