Re: [squid-users] squidclient mgr:info

Good day,
Special thanks to Hasanen AL-Bana.
Thank you for swift response. Do you mean ICP or HTCP is useful only if i
have another cache server WITHIN my network?

Please, what information do want me to supply you so that you can help
fine tune my squid performance because am already having "headache" with
squid rebuilding store most of the time (see my post "Cache log errors").
Regards
Yomi
