LiteSpeed Web Server is an Apache-interchangeable, high performance, secure, easy-to-use web server. It can handle thousands of concurrent connections with a small memory footprint. Its security features also make it much less vulnerable to various attacks.
Dynamic Content Generation
LiteSpeed Web Server supports the following dynamic content generation methods:
Per-Directory Configuration File Support (.htaccess)
LiteSpeed Web Server provides the following security features:
Supports SSLv3/TLSv1. This product includes software developed by the OpenSSL Project for use in the OpenSSL Toolkit (http://www.openssl.org/)
Network bandwidth and request rate for a single IP address can be limited regardless of the number of connections.
Comprehensive control of concurrent connections allowed from a single IP address.
Apache mod_security compatible request filtering. Block known as well as potential attempts at SQL/script injection XSS attacks.
Access control rules can be set at server, virtual host, and per-directory (context) levels.
LiteSpeed Web Server shields CGI, Fast CGI and servlet engines from talking directly to web clients to ensure maximum reliability and performance.
LiteSpeed Web Server prevents bad CGI scripts from overloading the server by limiting the system resources CGI applications can consume.
LiteSpeed Web Server can run CGI scripts and Fast CGI applications in a chroot jail or a different user/group ID, minimizing possible damages from vulnerable scripts.
LiteSpeed Web Server is much less vulnerable to HTTP Denial of Service(DoS) and Distributed Denial of Service (DDoS) attacks thanks to IP-level throttling, connection accounting, and its outstanding performance and scalability.
LiteSpeed Web Server can run in a chroot jail.
LiteSpeed Web Server recovers from crashes instantly. LiteSpeed Web Server also runs completely in user space. Thus the server can easily switch between different versions without affecting the reliability of the operating system.
CGI, Fast CGI and Servlet engine run in their standalone processes, the reliability of web server is not affected by the quality of third party software.
LiteSpeed Web Server is designed to be interchangeable with Apache, the most popular server software on the Web. LiteSpeed Web Server can even run directly from Apache's configuration files.
LiteSpeed Web Server also uses the same syntax for distributed configuration files (.htacess) and URL rewrite rules, which makes migration as easy as setting the LiteSpeed Web Server document root to the same directory as Apache.
Currently, functionalities of the following Apache modules have been implemented:
