The Micro Focus Common Client (MFCC) provides a client-side networking framework for several components of your development and run-time environments.
It's used by COBOL web service proxy programs, the Interface Mapping Toolkit's service-deployment mechanism, Fileshare clients (when configured appropriately), various utilities such as cassub (depending on operating mode) , CICS Web Interfaceand CICS Web Services, and product components such as MFCS and ESCWA.
MFCC is configurable through its configuration file. By default, the file is named mf-client.dat, which is located in the bin subdirectory of your product install directory (Windows) or $COBDIR/etc (UNIX). You can use the MFC_CONFIG environment variable to override this and specify your own configuration file; set it to the absolute pathname of the configuration file to use.
Refer to mf-client.dat Configuration Options for details on how you can edit or enable advanced functionality, such as TLS support or Web service clients.
