How CICS Web support handles pipelining

A pipelined request sequence can be sent and received by CICS®. CICS as an HTTP server can receive a pipelined request sequence from a Web client, and CICS as an HTTP client can send a pipelined request sequence to a server.

CICS Web support handles pipelined request sequences, and the responses to them, as follows:

For CICS as an HTTP client, it is the application program's responsibility to ensure that any pipelined sequence of requests is idempotent. Pipelining explains idempotency. For the benefit of your application program's logic as well as for the benefit of the server, if you are not sure that a sequence of requests is idempotent, it is advisable to make separate requests, and wait for a response to each request before sending the next one.
