# To implement HTTPS Server and Client, only the two init methods need to be changed. HTTP Server and Client init:
#
# ```python
# # HTTP Server init
# HTTP_Server.init()
# # HTTP Client init
# HTTP_Client.init('http://' + str(wlan.ifconfig()[0] + '/resource'), callback=client_callback)
# ```
# HTTPS Server and Client init:
# ```python
# # HTTPS Server init
# HTTP_Server.init(port=443, keyfile='/flash/cert/prvtkey.pem', certfile='/flash/cert/cacert.pem')
# # HTTPS Client init
# HTTP_Client.init('https://' + str(wlan.ifconfig()[0] + '/resource'), callback=client_callback)
