Provides a base class for the CHttpFile and CGopherFile file classes. You never create a CInternetFile object directly. Instead, create an object of one of its derived classes by calling CGopherConnection::OpenFile or CHttpConnection::OpenRequest. You also can create a CInternetFile object by calling CFtpConnection::OpenFile.

The CInternetFile member functions Open, LockRange, UnlockRange, and Duplicate are not implemented for CInternetFile. If you call these functions on a CInternetFile object, you will get a CNotSupportedException.

To learn more about how CInternetFile works with the other MFC Internet classes, see the article Internet Programming with WinInet.
