I think that overall it's fine. I'm going to add minor restrictions to the
UP server before killing backup connections :
- ensure that it's not backup (otherwise it can make things worse when
you have multiple backup servers)
- ensure that its weight is > 0, otherwise it will not get any traffic
I'll also add some basic doc for this new option.
Thanks,
Willy
