Add an ssl no-default example
Add an ssl no-default example

I.e. an example of this:

    -> curl -kI -H "Host: valid.com" https://localhost
    HTTP/1.1 200 OK
    ...
    -> curl -kI -H "Host: invalid.com" https://localhost
    curl: (52) Empty reply from server

Whether this works or not depends on SNI.
