Handling network timeout in Qt

When dealing with `QNetworkReply`, it is prescribed to use timers to abort the connection. Here is my current code: ``` void ImageDownloader::download(QString imgUrl){ this->timeoutTimer = new QTimer(this); this->timeoutTimer->setSingleShot(true); this->timeoutTimer->setInterval(15000); connect(this->timeoutTimer, SIGNAL(timeout()), this, SLOT(timeout())); QUrl requestUrl(imgUrl); QNetworkRequest nwRequest(requestUrl); this->imageNwReply = this->nam->get(nwRequest); connect(imageNwReply,SIGNAL(finished()),this,SLOT(imgDownloaded())); connect(imageNwReply, SIGNAL(downloadProgress(qint64,qint64)), this->timeoutTimer, SLOT(start())); this->timeoutTimer->start(); } void ImageDownloader::timeout(){ qDebug()<<__FUNCTION__<<" Forced timeout!"; this->imageNwReply->abort(); } ``` The confusion I am facing is when should I start the timer? At times I have to make around 50 concurrent Get requests from `QNetworkAccessManager` but since there is throttling for maximum concurrent connections, at times it happens that some of the requests get timed out even before they have been processed. Is there a signal to know exactly when the processing for a request is started by `QNeworkAccessManager` so that I can start the corresponding timer only then? One possible solution might be to implement a Queue of requests and have only the maximum possible connections to process but I am looking for a cleaner solution
