HTTP POST method

Use a network sniffer and see what is different between your implementation and a web browsers.

I captured packets sent by internet browser and my program by WinDump, and everything was the same, except some values from HTTP header.

Now I used QNetworkAccessManager instead of QHttp and it works, but i don't know why :P

So the data sent is exactly the same as before, as verified by WinDump?

[Macok]

Data are the same, but header is quiet different (QNetworkAccessManager sends also information about User-Agent etc.).

[squidge]

Right, so you do know why. The header is different!
