As you are not using ICP you also need to specify the no-query option.

Other than this it should work fine, but you might want to specify a
low peer connect timeout to speed up the failover process.

To make things more obvious you might want to use default only on the
actual default parent. This also have the benefit that access.log
will more clearly indicate failover conditions.

  cache_peer cache_peer1 parent 8080 0 default no-query
  cache_peer cache_peer2 parent 8080 0 default no-query
  peer_connect_timeout 2 seconds
