Remember FastCGI? (2021)

  If you find yourself with a scripted language where processing HTTP requests might be too slow or unsafe, I can still see some utility for FastCGI. For most of the rest of us, HTTP won, just write little HTTP webservers.

Without serious development effort, I would expect using an existing web server with FastCGI is faster than writing your own web server. It is also more secure as the FastCGI application can be run as a different user in a chroot, or a namespace based sandbox like a docker container.

I was thinking that.

Was FastCGI a child of a world where we had neither good library use ("import net/http"), nor (much) layering in front of the server (balancers / cdns / cloudflare etc). So it made sense to assume a production-level layer on the box itself was always needed?

I remember the vigorous discussions comparing security of Apache vs IIS etc
