title: QNetworkAccessManager timeout
body: <p>Presently I am working on an application which sends and receives file from remote server. To do network operation I am using QNetworkAccessManager.</p>
  
  <p>To upload a file I am using QNetworkAccessManager::put() and to download I am using QNetworkAccessManager::get() functions.</p>
  
  <p>While uploading a file I will initialize a timer with time out of 15 sec. if I upload a small file it will complete it within the time out period. But if I try to upload a file which is very large in size get time out. So how to decide time out for uploading of large file.</p>
  
  <p>Same in case of downloading of a large file. I get file in chunk by chunk in readyread() signal. Here also if I download a large file I get time out. So how to decide time out for uploading of large file.</p>
