What is OpenLiteSpeed?


OpenLiteSpeed (OLS) is a high performance, open-source web server, full of cutting edge features. With the event driven architecture and intelligent caching system, OpenLiteSpeed has the capability of increasing your site speed tremendously. Not only is OLS fast, but it also has security features that rival the best competition. Eventually, all of our OpenLiteSpeed documentation will be available on this site, but until then, you can find what you need in our knowledgebase.
