“The perfect web server” is kind of a subjective question but I’ll do my best.
First off, you need to ask yourself what you’re going to be doing with this web server. Are you going to be mainly serving static content? Proxying to something else that is service static content? How many visitors are you looking at?
My personal preference for “web server” these days is Nginx. Even if I am just using that as a proxy in front of a python app, I find it is fast, easy to configure, and has great documentation. I would suggest starting with reading some of our tutorials and then if you come back with some more specific questions I’m sure the community can help better!
