Oleg,
Pardon me! I re-checked the responseBody and something has definitely
changed since I added the "data" parameter to my POST as you recommended. I
decided to redirect the responseBody output to a .html file so that I could
easily examine it with my web browser. It now is a web page displaying, among
other things, the following messages.

Which looks like a temporary problem. Perhaps if I re-run my program, I may
get the response I am looking for. Any other suggestions?
