I was originally thinking "off by default", but only because of the
theoretical security implications of being automatically redirected to a URL
(possibly a different machine, etc.) that differs from what you expected.
Maybe I'm overthinking that, exaggerating the risk? If so -- if there's no
risk to automatically following redirection notices -- then is there any
value in having either configuration OR prompts for this behavior?
