Issue a QWK-packet-received confirmation request after a successful download

of a QWK packet (sending the received-file-length as a post parameter):
 http[s]://host/qwk.ssjs?received=<length>
If the file size matches the user's QWK packet size, the local (server-side)
QWK packet is deleted.
Passing an empty string to HTTPRequest.Post() since it requires a data
paramater. :-( Using Post rather than Get 'cause the chicken hath spake:
"<echicken> I think POST is probably technically the more correct way to do it"
