I am descending from TTMSFMXCloudBase to implement XING-API calls.
XING sometimes provides call results only by differing response codes - this is per REST architecture a valid way to send reponse information.
The httpsput, httpspost and httpsget calls of TTMSFMXCloudBase do not provide any possibility to get the repsonsecode or responseheaders if I did not miss anything.
The possibility to get responsecode and responseheader information in TTMSFMXCloudBase descendents would be adding a lot of value to TTMSFMXCloudBase and should not be too much of coding.
