LiteSpeed Load Balancer (LSLB) can forward requests based on request content as well as session stickiness preference.
LiteSpeed Load Balancer can help scale your application beyond one server deployment, as well as improve the reliability of your service in case of hardware failures.
Security
LiteSpeed load balancer is designed to be a secure load balancer. With chroot jail, connection accounting, strict HTTP request checking, IP level bandwidth throttling, and URL context filtering, DoS effects will be minimized and the backend cluster is pro
