Main features:
LiteSpeed Web Server is a HTTP/1.1 web server with HTTP/1.0 backward compatibility. Notable HTTP/1.1 features are:
- Basic Authentication (htpasswd and LDAP backend)
- Entity Tag
- Range/Multi-range Request
- GZIP content transfer encoding
- 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.
- 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 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 files contents. Not only will LiteSpeed help you reduce your hardware costs, but it will also help you reduce bandwidth costs!
- Unlike Apache, LiteSpeed intelligently enables Keep Alive for media content such as images, CSS, and JavaScript, but does not enable it for dynamic content (e.g. PHP). Preserve the RAM in your server for other tasks!
