module VCR
# @private
module Net
# A Net::HTTP response that has already been read raises an IOError when #read_body
# is called with a destination string or block.
#
# This causes a problem when VCR records a response--it reads the body before yielding
# the response, and if the code that is consuming the HTTP requests uses #read_body, it
# can cause an error.
#
# This is a bit of a hack, but it allows a Net::HTTP response to be "re-read"
# after it has aleady been read. This attemps to preserve the behavior of
# #read_body, acting just as if it had never been read.
