# Writes a Rack response to your client using the HTTP/1.1 specification.
# You use it by simply doing:
#
# status, headers, body = rack_app.call(env)
# http_response_write(socket, status, headers, body)
#
# Most header correctness (including Content-Length and Content-Type)
# is the job of Rack, with the exception of the "Date" and "Status" header.
