Use openssl to Issue Raw HTTP Requests

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 22.214.171.124... Connected to algol.plymouth.edu. Escape character is '^]'. GET / HTTP/1.1 Connection closed by foreign host.
openssl (which is a toolbox in its own right) can step
openssl s_client -connect www.plymouth.edu:443
