i made a request to http://yandex.ru/yandsearch?text=123&lr=213 with proxy

{
proxy.setType(QNetworkProxy::HttpProxy);
proxy.setHostName(QString("46.42.44.212"));
proxy.setPort(3128);
QNetworkProxy::setApplicationProxy(proxy);
}

and qwebview

MyNetworkAccessManager *nam = new MyNetworkAccessManager();
nam->setCookieJar(new QNetworkCookieJar());
ui->webView->page()->setNetworkAccessManager(nam);

QWebSettings::globalSettings()->setAttribute(QWebSettings::AutoLoadImages, true);
QWebSettings::globalSettings()->setAttribute(QWebSettings::JavaEnabled, true);
QWebSettings::globalSettings()->setAttribute(QWebSettings::JavascriptEnabled, true);
QWebSettings::globalSettings()->setAttribute(QWebSettings::PluginsEnabled, true);

ui->webView->page()->setLinkDelegationPolicy(QWebPage::DelegateAllLinks );

ui->webView->setUrl(QUrl("http://yandex.ru/yandsearch?text=123&lr=213"));

for cookies i have my MyNetworkAccessManager in createRequest(Operation op, const QNetworkRequest &request, QIODevice *outgoingData)

if(static_cast<QNetworkRequest::LoadControl>request.attribute(QNetworkRequest::CookieLoadContr olAttribute, QNetworkRequest::Automatic).toInt()) == QNetworkRequest::Automatic)
{
if (this->cookieJar())
{
QList<QNetworkCookie> cookies = this->cookieJar()->cookiesForUrl(request.url());
if (!cookies.isEmpty())
{
myReq.setHeader(QNetworkRequest::CookieHeader, qVariantFromValue(cookies));
}
}
}

and always get same error

"error string: Operation canceled"
"error url: http://yandex.ru/showcaptcha?retpath=http://yandex.ru/yandsearch?text=123&lr=213&t=0/1314734922/b029d1247fd1f0e0111636a2a04cc9f9&cc=1&"

Does it work properly if you don't use the proxy?

Yes, without proxy everything is ok. But point is to use connection only with proxy, because of ip address. And without proxy i don't have redirect to captcha page.
