High level API for processing file uploads.
This class handles multiple files per single HTML widget, sent using
multipart/mixed encoding type, as specified by
RFC 1867. Use parseRequest(HttpServletRequest) to acquire a list of FileItems associated with a given HTML widget.
Individual parts will be stored in temporary disk storage or in memory, depending on their size, and will be available as FileItems.
Deprecated:
1.1 Use ServletFileUpload together with
            DiskFileItemFactory instead./**
