Re: [squid-users] Too many queued ntlmauthenticator requests (26 on 5)

Thank you Amos,

do you think if I add the " auth_param ntlm children 20 " on the my
squid.conf may solve my problem ?

with value 20 my squid can supports up to 40 new client connections
right ? might occur any slow or something??

there is other way for I accomplish this change ?

thank you!
