LiteSpeed Web Server (LSWS), is a proprietary web server software. It is the 5th most popular web server, estimated to be used by 6.4% of websites as of April 2020.[3] LSWS is developed by privately held LiteSpeed Technologies. The software uses the same configuration format as Apache HTTP Server and is compatible with most Apache features.[4][5] An open source variant is also available.[6]

LSWS was released in 2003, and in August 2008 it became the 16th most popular web server.[7] In November 2016, LiteSpeed's market share grew from 0.39% to 3.29%, increasing its position from 10th to 4th most popular web server according to Netcraft.[8] In 2017, a team from Hong Kong Polytechnic University found it to be one of the six most popular web servers,[9] and it was estimated by a team at RWTH Aachen University to be running 9.2% of all HTTP/2-enabled websites.[10] As of April 2020, LSWS was used by 69.3% of websites using QUIC[11] and 47.6% of websites using HTTP/3.[12]

Features

LSWS is compatible with commonly-used Apache features, including mod_rewrite, .htaccess, and mod_security. LSWS can load Apache configuration files directly and works as a drop-in replacement for Apache while fully integrating with popular control panels. LSWS replaces all Apache functions, but uses an event driven approach to handle requests.[13]

History

LiteSpeed Technologies was founded in early 2002 by a team of engineers led by George Wang. On July 1, 2003, LiteSpeed Web Server was officially released as a full-featured web server. In 2007, LiteSpeed Web Server became LiteSpeed Web Server Enterprise and was configured to be an Apache drop-in replacement. In that same year, the web server integrated with cPanel, DirectAdmin, and Plesk. LiteSpeed Web Server officially began supporting HTTP/2 in 2015 with version 5.0, and also released LSCache (cache plugin for WordPress) with ESI in version 5.0.10.[1] In 2017, LSWS released QUIC support.[14] In July 2019, LSWS announced support for HTTP/3.[15]
