Handler
Promise
representing the asynchronous Response
of the given request
.
If any (asynchronous) processing goes wrong, the promise still contains a Response
(probably from the
4xx or 5xx status code family).
A handler that doesn't hand-off the processing to another downstream handler is responsible for creating the response.
The returned Promise
contains the response returned from the server as-is.
This is responsibility of the handler to produce the appropriate error response (404,
500, ...) in case of processing error.
Note: As of Promise 2.0 implementation, it is not permitted to throw any runtime exception here. Doing so produce unexpected behaviour (most likely a server-side hang of the processing thread).
