Change subject: cache_misc: send randomized pass traffic directly to t1 backends
......................................................................
cache_misc: send randomized pass traffic directly to t1 backends
backend_random is only used for (and for all) "pass" traffic (both
explicit and hit for pass). For tier-2 frontends, the jump of
this traffic through tier-2 backends before hitting tier-1
backends is pointless and wasteful: sending it directly to tier-1
backends accomplishes the same thing more efficiently and still
makes use of our IPSec protection for x-dc connections. In the
long run we'll go one step further and have all frontends
(regardless of tier) contact the applayer directly for pass
traffic and not need "backend_random" at all, but that's blocked
on further x-dc crypto work.
Bug: T96847
