Hepsia Advanced Features
The Advanced tab gives you swift access to an array of advanced tools, among them the Memcached distributed memory caching system and the Varnish Cache web application accelerator, which will help you optimize your web sites and apps without having to log out of the Control Panel. Based on the website hosting package, these tools are either included by default or are available in the form of easily gettable upgrades. InnoDB and NodeJS support is offered as well.
Varnish
Varnish Cache is a web application accelerator also popular as a caching HTTP reverse proxy. You can install it in front of any web server that speaks HTTP and configure it to cache the content. Varnish Cache is really, really fast and will boost the speed of your website. One of the key virtues of Varnish Cache is the flexibility of its domain-specific language, VCL, which allows you to choose how incoming requests should be dealt with.
Memcached
Memcached is a general-purpose distributed memory object caching system for boosting the speed of dynamic database-driven websites. It is used to lower the number of times an external data source (such as a DB or API) is read by caching data and objects in RAM. The Memcached distributed memory caching system uses a client/server architecture. The Memcached system is used by some of the most traffic-hungry web sites on the World Wide Web and is supported by popular web apps like Joomla and WordPress.
Node.js
Node.js is a platform for building scalable network apps. Built on Chrome's JavaScript runtime, Node.js uses an event-based, asynchronous I/O model that makes it lightweight and efficient, perfect for real-time content-heavy Internet apps. Node.js uses Google's V8 JavaScript engine, libUV, and several built-in libraries.
InnoDB
InnoDB is the default database engine for the MySQL open-source DBMS. A database engine is the principal software component that a DBMS uses to create, retrieve, update and delete data from a database. Its latest edition features considerable improvements in efficacy, reliability and functionality. InnoDB provides the standard ACID transaction features, along with declarative referential integrity support. InnoDB is included as standard in most binaries distributed by MySQL AB.
