LiteSpeed Web Server (LSWS) comes equipped with features that directly correspond with Apache’s popular functionalities, such as its Rewrite Engine and ModSecurity. LSWS can even load Apache’s configuration files seamlessly. Regarded as a drop-in replacement, LiteSpeed can integrate fully with control panels written for Apache, including, but not limited to, cPanel, Plesk, and DirectAdmin.
