Yep. I didn't know what this was either.
We use a "reverse proxy server" called Traefik v2 (The "v2" is VERY important!!! Many tutorials online are still for v1; all that code totally doesn't work anymore)
Before you start to learn about Traefik or reverse proxy servers in general, I think you'd benefit from learning what "HTTPS" really is. At the end of the day, the reason we're using this thing called Traefik in our infrastructure is to make it so the traffic sent to and from our backend REST API is secured with HTTPS.
No joke, this comic is the way I learned HTTPS. I think it's awesome 🤣
