SAP Web Dispatcher (New)

Use

The SAP Web Dispatcher is used as a "software Web switch" between the Internet and your SAP System that consists of one or more SAP Web AS. This ensures that there is only one point of entry for HTTP(S) requests in your system.

For every request, the SAP Web Dispatcher decides whether it should be forwarded to a J2EE server or an ABAP server. It recongnizes requests from stateful transactions (such as an ordering transaction in an Internet shop) and forwards these on to the processing server.

Furthermore, the SAP Web Dispatcher balances the load, so that the request is always sent to the server with the largest capacity.

Using the SAP Web Dispatcher simplifies administration, since there is only one point of entry (IP address, HTTP port etc.) to the SAP System.
