/**
* Interface which provides additional methods for dealing with multipart
* content within a servlet request, allowing to access uploaded files.
* Implementations also need to override the standard ServletRequest
* methods for parameter access, making multipart parameters available.
*
* A concrete implementation is DefaultMultipartHttpServletRequest. As an
* intermediate step, AbstractMultipartHttpServletRequest can be subclassed.
