 Communication Between SAP Web Dispatcher and ABAP Servers Locate this document in the navigation structure

 

For SAP Fiori search, transactional apps and fact sheets, SAP Web Dispatcher forwards the following types of requests to the ABAP front-end server and the ABAP back-end server:

  • ABAP front-end server:

    • HTML requests

    • OData requests

  • ABAP back-end server:

    • InA search requests (SAP Fiori search fact sheets only)

For communication between SAP Web Dispatcher and the ABAP servers, HTTPS connections are established.

Activities

To set up the connections between SAP Web Dispatcher and the ABAP servers, you must make the following settings:

  • You must configure HTTP security session management for the ABAP front-end server and for the ABAP back-end server.

  • You must configure the ABAP front-end server and the ABAP back-end server for supporting SSL.

  • You must define routing rules for SAP Web Dispatcher.

  • If you use X.509 client certificates for authentication at the ABAP servers, you must configure a trust relationship between SAP Web Dispatcher and the ICM of the ABAP servers.

  • For fact sheets, you must configure SAP Fiori Search. For more information, see Configuring SAP Fiori Search (Fact Sheet).

To ensure confidentiality and integrity of data, SAP recommends protecting HTTP connections by using Transport Layer Security (TLS) or Secure Sockets Layer (SSL). For information about setting up communication encryption for SAP NetWeaver, see the following documentation:

  • For SAP NetWeaver 7.31, see the SAP Help Portal at   http://help.sap.com/nw731   Security Information   Security Guide   Network and Communication Security   Transport Layer Security  .

  • For SAP NetWeaver 7.4, see the SAP Help Portal at   http://help.sap.com/nw74   Security Information   Security Guide   Network and Communication Security   Transport Layer Security  .

Note Note

A token-based protection against Cross-Side Request Forgery (CSRF) is active by default in SAP Gateway and SAP HANA XS Fiori OData services. It protects all modifying requests.
