Differentiate HTTP vs HTTPS

[ldionmarcil]

Continuation of a discussion we had in this thread.

Please describe your feature request:

It would be very useful for interactsh so differentiate between cleartext and encrypted protocols, ie HTTP vs HTTPS. This is especially useful when testing for protocol downgrade via open redirects.

Describe the use case of this feature:

For example, if you get a callback on https://interactsh.com (TLS), then make the endpoint hit a 301 redirect to http://interactsh.com, both callbacks will show as the protocol "HTTP". As a result it is impossible to check if protocol downgrade worked.
