ConfigOption/pool host list
pool_host_list
Defines an ordered list of pools to use for pooled mining. The first pool that is giving valid work is used. Connections are maintained with all pools listed.
If the miner fails over to a pool down the list, it will return to the first pool when that pool starts working again.
Default
No default. If not present then pool_host is used instead.
