If a client tries to send some extra data, they will receive an **error** response.

For example, if the client tries to send the form fields:

//	go run ../../mkzip.go ../../zoneinfo.zip
//
// We use this program instead of 'zip -0 -r ../../zoneinfo.zip *' to get
// a reproducible generator that does not depend on which version of the
// external zip tool is used or the ordering of file names in a directory
// or the current time.
