qdeclarative/qqml xmlhttprequest: wrong method for redirects

4.8.5: QDeclarativeXMLHttpRequest handles redirects internally. But after receiving a redirect answer it only changes the url and creates a new request. In particular, the method of the request is not changed. This is wrong : according to rfc 2616 (http://www.ietf.org/rfc/rfc2616.txt, section 10.3.4 "303 See Other") result of 303 redirection should be always a new GET request.

It is a serious problem. The redirect is simply wrong (you request a wrong resource; if your original request was POST QDeclarativeXMLHttpRequest requests wrong POST+new url instead of correct GET+new url).

I attach a patch which we use for qt 4.8.5.

5.1.0: By looking at the source (qtdeclarative/src/qml/qml/qqmlxmlhttprequest.cpp and qtquick1/src/declarative/qml/qdeclarativexmlhttprequest.cpp) in Qt5 there is exactly the same problem both in QtQuick1 and QtQuick2.
