relayd: backups when using relay?

[Johan Ström]

Hi list

I'm looking at the relay  (not redirect) feature of relayd (4.4), but  
cannot figure out how to use backups/fallbacks when doing relaying?
With redirect I just add another forward directive, but this doesn't  
seem to work for relays? Cannot find anything in docs mentioning this  
(with regards to relays).

Any pointers?

Thanks
Johan
