Client sends "CONNECT", then a proxy responds "200 Connection Established". libcurl calls WebCore::headerCallback. In WebFrameLoaderClient::dispatchDecidePolicyForResponse(), response.mimeType() is null. WebView::canShowMIMEType() returns false. Then, the request is canceled. A following bug might be same problem. Bug 20481 – [Curl] Cannot log on google with proxy

AFAIK, curl port is used only by WinCairo port. CC-ed the experts.
