But how you can do this inside redundant-load-balance block?
It seems out of scope to reset REST-HTTP-HEADER until all available
modules (inside the redundant-load-balance) are executed.I know that
single module doesn't know that is inside of redundant-load-balance
section but it seems wrong from my side do this because this means
something like this:
redundant-load-balance {
       rest1       update control {          &REST-HTTP-Header = "X-
Header: XXX"      }      rest2
that is wrong as syntax.
I will try to add an option for this, probably is the more easy way to
use it.
