Streamline the loop construct

- Add support for HTTPS
  - Add support for IPv6
  - Add support for more than one path argument
  - Properly identify the Location header in the HTTP response
  - Properly identify the destination host in the Location header
  - Leverage normalized IP address comparison
  - Avoid processing the HTTP response body, possibly "endless"
  - Add the found IP address as a new scan target (optionally)
