Explain https URI scheme?
Answer: https is a URI scheme which is, away from the scheme token, syntactically similar to the http scheme utilized for normal HTTP connections, however which signals the browser to use an extra encryption layer of SSL/TLS to defend the traffic. SSL is particularly suitable for HTTP as it can give some protection even when only one side of the communication is authenticated. This is the case with HTTP transactions over Internet, where usually only the server is authenticated.
