| Subject: | Document which of X-Died and Internal-response responses should be retried |
It's not entirely obvious to me, in which case request should be retried due to network error.
seems X-Died header can contain /^read timeout/, /^EOF/, /^read failed/ and this mean request should be retried.
However I am not sure if it can contain other errors, which mean request should not be retried.
Also, not sure about 'Client-Warning' = 'Internal-Response' errors.
