HTTP server and utilities
QHttpEngine provides a set of classes that simplify the process of adding an HTTP server to a Qt application. This includes low-level classes for interacting directly with HTTP sockets and higher-level classes for building REST APIs. The library can also serve static files both from the local filesystem and from the Qt resource system.
