ECHTTP (pronounced somewhat like "easy HTTP" I'd say) is a simple single-file HTTP/HTTPS client library written in C.
This implementation is roughly based on http.h by Mattias Gustavsson, but has been refactored and improved, including TLS support, more than just GET and POST requests, and an easier API.
It uses TLSe for TLS (previously known as SSL) support.
