This manual describes how to set up a reverse proxy using IIS. A reverse proxy is used, for example, to make an HTTP server available via HTTPS.
Below you see a diagram of the result we want to achieve:
Install the IIS modules Application Request Routing (ARR) and URL Rewrite.
Create an IIS website or use the default site. Open the site and click on URL Rewrite.
Click on Add Rule and choose Reverse Proxy. Confirm when prompted to enable proxy functionality in the ARR module.
In Inbound Rules, enter the address of the internal server (including the port number). please note: this must be the address of the server that the reverse proxy refers to (not the address of the reverse proxy itself).
Click OK to confirm. The outbound rules do not need to be configured for Zenvoices. The reverse proxy is now active.
