WEBEM is a free, open source C++ Embedded web server.
Do you have a web page or two? Nothing fancy, perhaps, but a neat demonstration of what can be achieved with a handful of HTML tags? Do you have a sophisticated C++ Windows desktop application which now needs to be controlled and monitored remotely? So, without learning a whole new technology, let's give your application its own web page!
Webem is a web server that you can embed in your C++ application. It makes it easy to implement a browser GUI accessible from anywhere.
Webem is based on a minimally modified version of the boost::asio web server, and permits HTML code to execute C++ methods.
