QNetworkAccessManager and QNetworkReply::OperationCanceledError

hello!

i'm using a QNAM object to fetch a file over https. after the request it's required some time to compose an answer, usualy about a minute. this is a timing diagram of the request execution in firefox, request completes successfully. but when i try to query it using QNAM::get method, it returns in about 15 seconds, and QNetworkReply::error() returns 5 (OperationCanceledError). is there a way to manage request timeout?

i tried to set request header "Keep-Alive: timeout=120" but it changed nothing of course.

looks like there is no way for this. i had to use libcurl.
