[Fujii Hironori]

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.

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