telnet is a handy tool for examining a raw HTTP connection, but it
fails hard on HTTP over SSL:
ambackstrom@fsck:~:0$ telnet www.plymouth.edu 443
Trying 158.136.1.105...
Connected to algol.plymouth.edu.
Escape character is '^]'.
GET / HTTP/1.1
Connection closed by foreign host.
Turns out openssl (which is a toolbox in its own right) can step
in:
openssl s_client -connect www.plymouth.edu:443
