I currently use nginx for all my projects, which for me mostly consist of (1) serving static content and (2) proxying to gunicorn. My setups are usually not overly complicated, basic redirects for stuff like www/non-www or ssl/non-ssl, installing ssl certs can be a pain sometimes, and for the most part I use a lot of default settings and have never needed to go in-depth with tweaking settings.
Does somebody like me have a reason to check out Proxygen?
Maybe not today. We haven't open sourced a configurable proxy yet, so you wouldn't be able to do your redirects and some of these other features without writing C++ code.
If you're interested in how HTTP frameworks are designed and implemented, I'd definitely suggest checking it out though. This project is initially going to be more interesting to people integrating with HTTP quite directly.
