contact D9800 Technical support for a working bash script example.
Cisco Engineering or Test personnel may use internal downloader
tools employing one or more high level languages that do not have
the same restrictions as the command line syntax requirements
described here. Those languages support source file streaming into
a buffer, and the contents of the buffer is an input to the client
application specific HTTP(S) POST API implementation.
