Hi Purush,

if the server supports it this is possible through class ResourceResponse's 
expectedContentLength() method.

Let's see: 
WebCore/platform/network/ResourceResponseBase.h
WebCore/platform/network/qt/ResourceResponse.h

Example for ResourceResponse's usage:
WebCore/platform/network/qt/QNetworkReplyHandler.cpp
