RFC 8767 recheck timer

[Andreas Schwarz]

Hi,

I am currently testing the RFC 8767 related options in unbound to serve stale records.

RFC 8767 mentions in section 5

 >  *  A failure recheck timer, which limits the frequency at which a
 >    failed lookup will be attempted again.

I could not find any option related to this functionality in the unbound manual. All the other portions of the RFC seem to be covered, but not this one. Did I miss something or is this not implemented?

Cheers
Andreas
