# HTTP response class.
#
# This class wraps together the response header and the response body (the
# entity requested).
#
# It mixes in the HTTPHeader module, which provides access to response
# header values both via hash-like methods and via individual readers.
#
# Note that each possible HTTP response code defines its own
# HTTPResponse subclass. These are listed below.
#
# All classes are
# defined under the Net module. Indentation indicates inheritance.
