SAP Web Dispatcher Configuration Reference

Use

The following is to give you an example of how to configure your Web Dispatcher.

  • 1 SAP Web Dispatcher as proxy to map in- and outgoing requests for differing systems

  • 1 SAP Gateway server

  • 1 backend system

In the example below SAP Web Dispatcher listens at port 443 and transfers:

  • all requests which start with /sap/opu/odata/ to the Gateway system

  • all requests which start with /sap/public/bc or /sap/bc to the backend system
