Making asynchronous RESTful calls via z/OS Connect EE Merged

From and out of the mainframe, we want to be able to make RESTful systems that are made of applications and programs that talk in ASYNC technology.

    Thank you for raising this requirement. It is being closed as a duplicate of existing RFE 132443:
    http://www.ibm.com/developerworks/rfe/execute?use_case=viewChangeRequest&CR_ID=132443

    RFE 132443 was rejected on the basis that it lies outside the scope of z/OS Connect EE. There is a longer description in the comments of RFE 132443, but the summary is that:
    - REST is an inherently synchronous interaction pattern.
    - Building a framework of asynchronous interactions is outside the scope of z/OS Connect EE. Solutions for asynchronous interactions such as MQ already exist today.
    - For inbound APIs, there is nothing stopping you designing an asynchronous interaction spanning multiple, synchronous, REST requests (eg a POST that responds with a 202 and an ID, then a GET with the ID for the result). You could use z/OS Connect EE in front of an asynchronous messaging framework like MQ with help facilitate this
    - For outbound API calls, you can use the facilities in your application hosting environments to manage asynchronous calls, eg using the CICS Async API to wrap calls to z/OS Connect EE's API requester.
