SAP Web Dispatcher
The SAP Web Dispatcher acts as a Single Point Of Access to the SAP System for users acessing the system via Browser (IE, FF). Therefore, it is located between the Internet / Intranet and the SAP System. The Web Dispachter acts as a load balancer and can redirect, reject or accept connections. When it accepts a connection, it balances the load to ensure an even distribution across the servers.
The SAP Web Dispatcher(SAP WD) is only useful in web-enabled scenarios. This is, when the SAP systems are accessed over HTTP(S). In a normal R/3 / ECC scenario the users will access the systems over the SAPGui and won't utilize the Web Dispatcher. The SAP WD can be used in ABAP/Java systems and in pure Java systems, as well as in pure ABAP systems. The usage is recommended when you use an SAP system with several SAP Web Application Servers for Web applications. The Web Dispatcher is associated with one Application Server (AS). This has to be the AS where the Message Server (MS) is running. One Web Dispatcher can only be associated with one AS.
The SAP WD acts as an Single Point Of Access (SPOA) and therefore, also as a Single Point Of Failure (SPOF). You can leverage the SPOA functionality to simplify your landscape
