# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# In Python, the following line of code does more than just connect:
# 
#      websockets.connect('ws://192.168.1.35/websocket')
# 
# It is connecting to 192.168.1.35 without using TLS.  If the URI starts with "wss://", then TLS should be used.
# But this URI begins with just "ws:/", so no TLS.

# Also, after connecting, a GET request is sent to the /websocket endpoint.
# In summary, the websockets.connect function is establishing the connection and it sends a GET request.

# First establish the connection.
# No TLS, use the default HTTP port 80.

# Add the standard WebSocket open handshake headers that will be needed.
# (This adds the required HTTP request headers to the rest object.)

# Now send the GET request to /websockets.
