C\Flow is a CICS web support product that acts as a listener for TCP/IP requests made from a client, using a HTTP protocol, to a z/OS CICS region, passing data to applications that use either a CICS COMMAREA or channel and containers communication.

The client can be running on any hardware that can make a HTTP request over TCP/IP. Clients make a standard HTTP POST requests sending data in various formats. The C\Flow listener is configured to call a single program passing the data in the HTTP body. This gives you the ultimate in flexibility since you can develop a standard for communication between a client and CICS.
