libonion is a lightweight library to help you to create webservers in C programming language. These webservers may be a web application, expanding you own application to have some web functionality, or a fully featured webserver if you want.

Normally a new handler is created that can serve the data, reading it from a file, processing some data... but there are many default handlers included with the most standard needs.

The name onion comes from that idea that the path transversal is done using many layers: on one layer you set the auth control, on another you check the server hostname (so you can have virtual hosts) on another a regular expression sends you to one or another path... Check on examples for how to do it.
