Introduction to the CICS business logic interface

The CICS® business logic interface makes it possible to link to a web-aware business application, rather than invoking it through the CICS HTTP listener.

For example, a web server running on z/OS® can use the external CICS interface (EXCI) to link to an application using the CICS business logic interface. In this way, a web client can communicate with a CICS application through an intermediate web server, rather than making a direct connection to CICS.
