Exercise 3b: encryption

Do the same thing, but:

• Use https_server.py instead of http_server.py
• Navigate to https://localhost:4443/exercise1b.html instead of http://localhost:8000/exercise1b.html (note both the different number, and the extra s on the end of http)
• Use a slightly different tcpdump command:

sudo tcpdump -i lo -A 'tcp port 4443'
