 **Turtle** is a C++17-based lightweight network library for web server mainly on Linux. It abstracts the tedious manipulations on the socket into elegant and reusable classes. It allows a fast server side setup where the custom business logic could be specified for each client TCP connection in the form of a callback function. It now supports HTTP GET/HEAD request and response as well.
