**Drogon** is a C++11-based HTTP application framework. Drogon can be used to easily build various types of web application server programs using C++. **Drogon** is the name of a dragon in the American TV series "Game of Thrones" that I really like.
Drogon's main application platform is Linux. It also supports Mac OS and FreeBSD. Currently it does not support windows. Its main features are as follows:
* Support Http1.0/1.1 (server side and client side);
* Based on template, a simple reflection mechanism is implemented to completely decouple the main program framework, controller and view.
* Support for cookies and built-in sessions;
* Support back-end rendering, the controller generates the data to the view to generate the Html page, the view is described by a "JSP-like" CSP file, the C++ code is embedded into the Html page by the CSP tag, and the drogon command-line tool automatically generates the C++ code file for compilation;
* Support view page dynamic loading (dynamic compilation and loading at runtime);
* Very convenient and flexible path to controller handler mapping scheme;
* Support filter chain to facilitate the execution of unified logic (such as login verification, Http Method constraint verification, etc.) before the controller;
