Hepsia Advanced Features
The Advanced tab gives you quick access to a set of advanced tools, among them the Memcached distributed memory caching system and the Varnish Cache web accelerator, which will help you optimize your web sites and applications without needing to move away from the Control Panel. Depending on the website hosting package, these tools are either included by default or are offered in the form of easily gettable upgrades. InnoDB and NodeJS support is available too.
Varnish Cache is a web application accelerator also referred to as a caching HTTP reverse proxy. You can install it in front of any server that speaks the HTTP protocol and configure it to cache the contents. Varnish Cache is very, very fast and will make your website load much faster. One of the key strengths of Varnish Cache is the flexibility of its domain-specific language, VCL, which enables you to determine how incoming requests should be tackled.
Memcached is a general-purpose memory object caching system for boosting the load speed of dynamic database-driven web sites. It is used to lower the number of times an external data source (such as a database or API) is read by caching data and objects in RAM. The Memcached distributed memory object caching system uses a client'server architecture. The Memcached memory object caching system is employed by some of the most traffic-heavy websites on the web and is supported by popular CMSs like Joomla and WordPress.
InnoDB is the default database engine for the MySQL open-source RDBMS. A database engine is the primary software component that a DBMS uses to create, retrieve, update and delete data from a database. The latest release of InnoDB offers considerable improvements in performance, stability and usability. InnoDB provides the standard ACID database transaction features, as well as foreign key support. InnoDB is included by default in most binaries distributed by MySQL AB.
