 # The option below identifies how the ProxyList is treated.
 # only one option should be uncommented at time,
 # otherwise the last appearing option will be accepted
 #
 dynamic_chain
 #
 # Dynamic - Each connection will be done via chained proxies
 # all proxies chained in the order as they appear in the list
 # at least one proxy must be online to play in chain
 # (dead proxies are skipped)
 # otherwise EINTR is returned to the app
 #
 #strict_chain
 #
 # Strict - Each connection will be done via chained proxies
 # all proxies chained in the order as they appear in the list
 # all proxies must be online to play in chain
 # otherwise EINTR is returned to the app
 #
 #random_chain
 #
 # Random - Each connection will be done via random proxy
 # (or proxy chain, see  chain_len) from the list.
 # this option is good to test your IDS :)

 # Make sense only if random_chain
 #chain_len = 2
