You can also use SSL for connections where an intermediary server is used. As the intermediary server, you can use the SAP Web Dispatcher or other Web proxy. A typical scenario is to place the intermediary server in the DMZ and the AS Java in the intranet zone.
Depending on the proxy used, options exist to use either an end-to-end SSL connection or to terminate the connection on the intermediary server and establish a new one to the backend system. See the figure below.
Using SSL With an Intermediary Server
In this documentation, we describe the configuration when using the SAP Web Dispatcher as the intermediary server. See Configuring SSL When the SAP Web Dispatcher is the Intermediary Server.
