What are the key features of the POCO C++ libraries?

The POCO C++ libraries provide a comprehensive set of C++ class libraries for building networked applications. Key features include support for HTTP, FTP, and WebSocket protocols, as well as data access, XML parsing, and JSON handling.

Can you explain how to set up a simple HTTP server using POCO?

Sure! To set up a simple HTTP server using POCO, you need to include the necessary headers, create an HTTPServer instance, and define a request handler. Would you like a code example?

Yes, please provide a code example.

Here's a basic example:

#include <Poco/Net/HTTPServer.h>
#include <Poco/Net/HTTPServerRequest.h>
#include <Poco/Net/HTTPServerResponse.h>
#include <Poco/Net/HTTPRequestHandler.h>
#include <Poco/Net/ServerSocket.h>
#include <Poco/ThreadPool.h>

class SimpleRequestHandler : public Poco::Net::HTTPRequestHandler {
public:
    void handleRequest(Poco::Net::HTTPServerRequest& request, Poco::Net::HTTPServerResponse& response) {
        response.setContentType("text/html");
        std::ostream& out = response.send();
        out << "<h1>Hello, POCO!</h1>";
    }
};

int main() {
    Poco::Net::HTTPServer server(new Poco::Net::HTTPRequestHandlerFactory<SimpleRequestHandler>(), Poco::Net::ServerSocket(8080), new Poco::Net::HTTPServerParams);
    server.start();
    std::cout << "Server started on port 8080" << std::endl;
    Poco::ThreadPool::defaultPool().join();
    return 0;
}

This code sets up a simple HTTP server that responds with "Hello, POCO!".

What are some common use cases for POCO libraries?

Common use cases for POCO libraries include developing web applications, RESTful services, IoT applications, and any networked applications that require robust communication protocols.
