It is only called if the application's return iterable ('self.result') is an instance of 'self.wsgi_file_wrapper'. This method should return a true value if it was able to actually transmit the wrapped file-like object using a platform-specific approach. It should return a false value if normal iteration should be used instead. An exception can be raised to indicate that transmission was attempted, but failed. NOTE: this method should call 'self.send_headers()' if 'self.headers_sent' is false and it is going to attempt direct transmission of the file.

It's also the base class for CGIHandler, which just uses sys.stdin, os.environ, and so on. The constructor also takes keyword arguments 'multithread' and 'multiprocess' (defaulting to 'True' and 'False' respectively) to control the configuration sent to the application. It sets 'origin_server' to False (to enable CGI-like output), and assumes that 'wsgi.run_once' is False.

It does not take any initialization parameters, but always uses 'sys.stdin', 'os.environ', and friends. If you need to override any of these parameters, use BaseCGIHandler instead.
