Redirect All HTTP Traffic to HTTPS in Express to Ensure All Responses are Secure

In the previous lesson, we disabled http in favor of https. In this lesson, we'll learn that the default protocol for web browser is http, and we therefore need to provide an http endpoint that redirects the browser to https. We'll do that by setting up a small express application whose sole responsibility is to redirect http urls to https. In doing so, we'll accidentally reintroduce the transmission of our session id over http, which we'll need to fix in our next lesson.
