Hi Francis,

Thanks. I have the two sites "mostly" working now (full config below),
but could you please expand on your comment ""listen 8001 ssl;" means
that nginx will listen for https, so you must make requests to port 8001
using https not http."

My problem is that app/server A (static html) is working perfectly, but
app/server B works only if the user's browser requests specifically
"https://... ", but returns a "400 Bad Request // The plain HTTP request
was sent to HTTPS port // nginx" if the browser requests http (which I
believe is the default for most browsers if you paste or type just the
URL into them.)

In other words, the last few lines of the config. work for port 80
(sends seamlessly the 301, then the content), but not for port 8084
(sends only the 400.)

Many thanks -- Paul
