LiteSpeed Web Server
LiteSpeed Web Server (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 — replacing Apache in less than 15 minutes with zero downtime. Unlike other frontend proxy-based solutions, LSWS replaces all Apache functions, simplifying use and making the transition from Apache easy while also allowing your team to move confidently with little-to-no retraining.
