What is the SAP Web Dispatcher?
The SAP Web Dispatcher is the entry point for HTTP(S) requests into your system, which consists of one or more NetWeaver application servers.
It combines the advantages of a "software web switch", a "reverse proxy" and an "application gateway".
The SAP Web Dispatcher contributes to security by accepting/denying incoming connections and ensures an even distribution of requests across the servers.
You can use the SAP Web Dispatcher in ABAP/Java systems and in pure Java systems, as well as in pure ABAP systems.
