-=================
+# Simple-Web-Server
 
 A very simple, fast, multithreaded, platform independent HTTP and HTTPS server and client library implemented using C++11 and Asio (both Boost.Asio and standalone Asio can be used). Created to be an easy way to make REST resources available from C++ applications. 
 
 See https://gitlab.com/eidheim/Simple-WebSocket-Server for an easy way to make WebSocket/WebSocket Secure endpoints in C++. Also, feel free to check out the new C++ IDE supporting C++11/14/17: https://gitlab.com/cppit/jucipp.
