Specific classes for requests and replies make common communication easy, while allowing the developer to customize particular requests. This is why. A factory can also be set in certain frameworks that support multiple connections, such as QNetworkAccessManager. How then, without some complex response routing mechanism in a single shared SLOT can a single QNetworkAccessManager be used to handle multiple, and different network requests?

The overall idea is that eventually QNetworkAccessManager, which is meant to generally be one-per-application, must be made thread-safe in order to fulfill this desired use. More specifically, I used QtcpSocket for the connection. For concurrent programming you have threading primitives like mutex, read-write lock, wait conditions, semaphores, as well gradually higher-level APIS - thread pools for example, ending with Qt Concurrent.
