All; Recently facing issue of squid stop working. it was working fine when there was little load on it. Our system administrator configure group policy to enabled proxy on all desktops with exception in proxy settings to local network. Reason to increase load on proxy is; Google chrome browser - when opened, it try to open chrome sign-in page which redirect to client1.google.com and so on. all these request get denied on proxy. Same with IE's bing home page try to connect MS site.
So I carry out following changes to squid config file Cache_dir value from 1024 to 10240. Since we have Kerberos auth cofnigured for SSO, I also increase auth_param negotiate children from 10 to 20. after this it start working as of now. I need to know what all caution I need to take more to avoid further issue. attached is squidclient o/p and squid.conf for analysis.
