I'm gonna need to make a web server backend software thing for distributing files related to playtesting. How, uhh, do people make server software nowadays? Asp.net? Rust? I've never felt so out of my depth before. Turns out there's a lot involved with making a web backend... 
@amara Just out of curiosity - what is that you're doing if you can't use some existing lightweight solution (like nginx, or even python's http.server), and have to roll your own?
@ticho These are mostly just for serving static files, right? I don't know much about web dev, so correct me if I'm wrong. What I need requires several people (10-20 people) uploading and downloading things like log and gameplay files through a game.
@amara That's still just static content - or do you need the webserver to generate pages - or other files - on the fly, as the requests come in?
@ticho Hmm... I suppose not! I didn't think of using something like that. I'll look into it, thanks.
