Description
QNetworkAccessManager fails to connect through a HTTP proxy (in my case a Basic auth proxy) if the HTTP 407 Proxy Authentication Required message from the proxy server uses chunked encoding.
Response parsing fails in the QHttpNetworkReplyPrivate::parseStatus function in this snippet:
if (status.length() < minLength
|| !status.startsWith(httpMagic)
|| status.at(dotPos) != '.'
|| status.at(spacePos) != ' ') {
// I don't know how to parse this status line
return false;
}
The problem is that at this point, `status` contains the length of the current chunk in hex, but the code tries to interpret this as a simple HTTP header and fails. After this error, the connection to the server is closed immediately.
This is the HTTP conversion that occurs:
