OpenResty

OpenResty is the Nginx web server bundled with LuaJIT and libraries that let small programs run inside the request cycle. This tag collects guides about building feeds, redirects and other lightweight endpoints directly in the web server. Articles explain how to fetch data from an internal location, keep the result in a shared memory zone and return the right content type with a validator. They also cover escaped XML, stale fallbacks during upstream outages, private internal locations and configuration tests before every reload. The advice helps teams publish a dependable feed from the server they already run and connect it to auto-posting tools.
