The document discusses SAP Web Dispatcher 7.40, which is a load balancer that provides intelligent load distribution for SAP Portal. It can handle stateful or stateless sessions over HTTP or HTTPS invisibly to clients. It supports round-robin load distribution for non-SAP backends like Tomcat. It also allows for multiple SSL certificates to handle multiple domains and backends. SAP Web Dispatcher provides reliability, security, and high performance to handle thousands of concurrent users. It includes features like maintenance mode, custom error pages, and is free to use with an SAP license.
