Hi @all,

While reading the Retry-After specs I was guessing...

if we had to reboot the retry-after header, would we use the HTTP-date
 or the unix-timestamp syntax?
iiuc the HTTP-date format was inherited from RFC 822 with the goal of
being human-readable.

Thanks for your feedback,
and have a nice day,
R.
