[Interest] Can't download file with QNetworkAccessManager: "connection closed"

[Nikos Chantziaras]

I have a weird problem. I am unable to download a file from a specific 
server (ran by sourceforge) using QNetworkAccessManager and 
QNetworkRequest. Example:


   this->fNetManager = new QNetworkAccessManager(this);
   connect(this->fNetManager, SIGNAL(finished(QNetworkReply*)),
           SLOT(fReplyFinished(QNetworkReply*)));

   QNetworkRequest request(QUrl("http://qtads.sf.net/COPYING"));

   this->fReply = this->fNetManager->get(request);
   connect(this->fReply, SIGNAL(error(QNetworkReply::NetworkError)),
           SLOT(fErrorOccurred(QNetworkReply::NetworkError)));


The fReplyFinished() slot:


   void Foo::fReplyFinished(QNetworkReply* reply)
   {
       if (reply->error() != QNetworkReply::NoError) {
           qDebug() << this->fReply->errorString()l
           return;
       }
   }


This result in:

   Connection closed

being printed. It's impossible to download the file. If I use another 
server (something not hosted by SourceForge), all is fine.

Using wget:

   wget http://qtads.sf.net/COPYING

works just fine. Using a simple Python program:

   import urllib2
   response = urllib2.urlopen('http://qtads.sf.net/COPYING')
   html = response.read()

also works just fine. The only one not able to fetch the file, is Qt. 
Any ideas on why this fails?

I'm on Qt 4.8.5, on Gentoo Linux AMD64.
