2.1.2 HTTP Transport

The HTTP transport based RDG protocol is transported by an HTTPS connection. By default the RDG server listens on the URL HTTPS Binding URL with port 443. However, the port number can be configured to a different value, see section 3.1.1 for details.

When the RDG server connects with a reverse proxy, the connection from the RDG client is terminated and another connection to the RDG server is created, over which data is relayed. The connection between the reverse proxy and the RDG server can then be over HTTP without SSL, for which the RDG server also binds on the HTTP binding URL.
