You should do this in the __call__() method. This is the default view of an
advanced IFile implementation of mine:

class AutoFileView(BrowserView):
   def __call__(self):
      self.request.response.setHeader('Content-Type',
                                            self.context.contentType)
      self.request.response.setHeader('Content-Length',
                                            self.context.getSize())
      return self.context.data
