|LiteSpeed Web Server Features|
LiteSpeed Web Server can operate with an Apache configuration file. Most commonly used Apache features have been implemented. Some Apache-compatible features including .htaccess, mod_rewrite, mod_security, and mod_frontpage are available exclusively on LiteSpeed Web Server and cannot be found in other light-weight web server software.
Web Hosting Control Panel Compatibility
LiteSpeed Web Server is able to seamlessly function as a drop-in Apache replacement for servers with control panels such as cPanel, Plesk, DirectAdmin, and Ensim. LiteSpeed Web Server can be configured to automatically update its configuration when any changes to the server’s httpd.conf file are made. LiteSpeed gracefully restarts in such an event, with ZERO downtime.
Full-featured web server
LiteSpeed Web Server is a HTTP/1.1 web server with HTTP/1.0 backward compatibility. Notable HTTP/1.1 features are:
Faster, more secure PHP
With our dedicated PHP LiteSpeed SAPI module, LiteSpeed Web Server is able to deliver a level of performance superior to that of mod_php as well as FastCGI. LiteSpeed supports PHP suEXEC without compromises of phpsuexec or suphp implementations. Every PHP process is run as the user who owns the account, dividing resource usage for easy identification, as well as greater separation from the web server (lshttpd) processes. In addition, LiteSpeed PHP allows PHP configuration in .htaccess, which is not available with phpsuexec or suphp implementations.
The Fastest and Easiest Ruby on Rails solution
Offer the fastest Ruby on Rails setup possible to your customers. With utmost security and reliability in mind for your RoR application, LiteSpeed is the best choice for RoR application hosting.
View real-time statistics for the entire server, or even at the virtual host level. Monitor the usage of every site on your server, and quickly find the site taking the most resources in real time! Real-time, flash-based graphs are available within the LiteSpeed console in both LiteSpeed Web Server Standard and Enterprise.
Compression is seamlessly configured in the tuning section of the LiteSpeed Console. Compression can be enabled on your specified types of data at any level you desire. With LiteSpeed, a balance can easily be achieved between CPU usage and the bandwidth usage benefits of gzip compression. LiteSpeed also offers the ability to create -Y´lsz¡ files which are pre-gzipped files, ready to be served to the user at any moment. These files are automatically updated with the change of the original file’s contents. Not only will LiteSpeed help you reduce your hardware costs, but it will also help you reduce bandwidth costs!
Smart Keep Alive
LiteSpeed Web Server is ready for the future IPv6 network.
Wide API Connectivity and web scripting languages support
LiteSpeed support a wide set of server API and scripting languages.
Unlimited Virtual Hosting
LiteSpeed Web Server can host an unlimited number of virtual hosts on one server.
LiteSpeed web server is designed with security in mind. With chroot jail, IP level bandwidth throttling, connection accounting, strict HTTP request checking, and URL context filtering, DoS effects are minimized and the application backend is properly fenced away from the HTTP request layer, greatly reducing vulnerability.
Not only does LiteSpeed offer built-in denial of service attack protection, but you can quickly identify the site that is the target of such an attack via the real-time statistics available in the LiteSpeed console.
External Application Firewall
LiteSpeed Web server forwards requests to external applications such as CGI, Fast CGI and Servlet engine to process/generate dynamic content. Usually each request requires one instance of the external application. Those applications may use a lot of system resources, and the performance of the whole system will be severely degraded when system resource consumption reaches a certain point, for example, when swapping space has been used. DoS attacks can be conducted by flooding the web server with concurrent requests to an external application that consumes a lot of system resources.
CGI Resources Consumption Limit
LiteSpeed web server limits system resources consumption for CGI applications in two ways and effectively fends off "fork bomb" attacks.
File system protection
LiteSpeed web server will serve a static file only if the following conditions are satisfied:
Chroot Jail (Enterprise Editions)
LiteSpeed web server can run in a chroot environment also known as a chroot jail with an automatic initial chroot environment setup. In a chrooted environment, the web server and its children processes cannot access the file system outside of the chroot jail. This protects the system from attacks caused by malicious code.
