# These examples provide some simple and quick ways to experiment
# with the differences between PHP curl requests and using the 
# curl command from a bash shell or script. The commands are arranged
# so they can be easily copy and pasted into a shell for experimenting.

# Use netcat listening locally for testing running netcat from one
# shell and execute the client requests from a separate shell. This
# can be useful to see newline characters and any additional characters
