I was coming from Lighttpd which at the time had a very similar config syntax to Nginx. It was pretty much a no brainer, considering I wanted to shift to an automated Letsencrypt renewal process at the same time.
Sadly I wrote some python web services for CGI (not django/flask) that cannot be run anymore, since NGINX only supports FCGI, rather than just CGI as far as I can tell
First time hearing of this! Thank you 😁
