CICS® Transaction Server for z/OS®, Version 3 Release 1 is designed to support your existing CICS Web support architecture for both Web-aware and non-Web-aware application programs. The EXEC CICS WEB API command changes are designed to allow existing Web-aware application programs that send and receive HTTP messages to work unchanged, until you choose to migrate them to take advantage of the enhancements that are now available. If you continue to use existing CICS Web support applications, note these migration points:
If you continue to use the DFHWBCLI
interface, note that the WBCLI_MEDIATYPE parameter is now required when using
the DFHWBCLI interface for SEND requests that use the HTTP POST method (requests
where WBCLI_FUNCTION_SEND and WBCLI_METHOD_POST are both set).
