# This class implements a simple way of constructing the HTTP headers dynamically
# via a Hash syntax. Think of it as a write-only Hash. Refer to HttpResponse for
# information on how this is used.
#
# One consequence of this write-only nature is that you can write multiple headers
# by just doing them twice (which is sometimes needed in HTTP), but that the normal
# semantics for Hash (where doing an insert replaces) is not there.
