The behavior for the proxy when port 80 and 443 are exposed is as follows:
* If a container has a usable cert, port 80 will redirect to 443 for that container so that HTTPS
* By default, if a container has a usable cert, port 80 will redirect to 443 for that container so that HTTPS
is always preferred when available.
* Set NO_HTTPS_REDIRECT=1 on the backend container if it is desired to serve both http and https from it.
* If the container does not have a usable cert, a 503 will be returned.
Note that in the latter case, a browser may get an connection error as no certificate is available
