Nope. Client (user agent or proxy acting on its behalf) makes connection to what it thinks is a server. E.g. <http://foo.bar.com/index.html>
But it happens to be reverse proxy, like nginx. Which forwards connection to actual http server in DMZ. E.g. to service-bar.intranet:8765/fooApplication/index.html
The first connection is described as origin, the second as local. E.g. when you want to make external link and send it by email, you need to know how your application looks from the outer-net. That’s normally passed by proxy to application in additional headers.
