I use squid to make a proxy server, and I have two parent proxy accounts here. i added them in the squid.conf cache_peer 10.10.2.54 parent 6666 6666 login=xxxa:xxxa no-delay no-query cache_peer 10.10.2.54 parent 6666 6666 login=xxxb:xxxb no-delay no-query my question is that: how can I know which account will be used by squid, can squid switch them automaticly? Because more bytes, more money. :) the squid works well, except we cannot connect to the internet sometimes, maybe the parent proxy cuts down when too much workload, I'm just guessing.
