IOLoop.spawn_callback, which makes the IOLoop responsible for the call. If it fails, the IOLoop will log a stack trace: # The IOLoop will catch the exception and print a stack trace in # the logs. Note that buffered in memory; if you need to handle files that are too large to comfortably keep in memory see the stream_request_body class decorator. In the demos directory, file_receiver.py shows both methods of receiving because the routing table does not change at runtime and is presumed to be permanent, while redirects found in handlers are likely to be the result of other logic that may change. To send a temporary redirect
