Sample HTTP POST server written with Python

HttpPostServer.py

# Run command:
#
#   $ python3 HttpPostServer.py
#
# Test POST with a complete file:
#
#   $ curl --data-binary "@small_file.bin" "http://127.0.0.1:8080/small.bin"
#
# Test POSTing a file progressively (chunked mode):
#
#   $ curl --header "Transfer-Encoding: chunked" \
#          --data-binary "@large_file.bin" "http://127.0.0.1:8080/large.bin"
