cpp-netlib is a powerful C++ network library that offers a variety of networking tools and components, including async_server.

The async_server is a component provided by cpp-netlib for building asynchronous servers. It is implemented based on the Boost.Asio library and offers a simple and efficient way to handle asynchronous network communication.

With async_server, you can easily create an asynchronous server to handle incoming connections and requests. Here is a simple example code:

#include <boost/network/protocol/http/server.hpp>

namespace http = boost::network::http;

struct hello_world;
typedef http::server<hello_world> server;

struct hello_world {
    void operator()(server::request const& request, server::response& response) {
        response = server::response::stock_reply(
            server::response::ok, "Hello, World!");
    }
};

int main() {
    hello_world handler;
    server::options options(handler);
    server server_(options.address("0.0.0.0").port("8000"));
    server_.run();
}

In this example, we have defined a hello_world structure that implements a function object for handling requests. When a request is received, the handling function will return a response containing “Hello, World!”.

Next, we defined a server object using the server type and passed the hello_world instance to its constructor function.

Finally, we start the server by calling the run method, which begins listening for incoming connections and requests.

In addition to its basic functions, async_server also offers many other features, such as support for HTTPS, custom handlers, and request filtering. You can learn more about the usage and features of async_server by referring to the documentation of cpp-netlib.
