Architecture
The Internet Communication Framework (ICF) is an integrated component of the ABAP Application Server (AS ABAP). The ICF provides the environment for handling HTTP requests in the ABAP work processes of an SAP system. ABAP AS can run both server functions and client functions for ICF communications. The Internet Communication Manager checks whether an HTTP call is to be sent to the JAVA environment or the ABAP environment in the Application Server, forwarding it to the ICF in the latter case.
