Good day, After checking the activities of my squid-cache proxy, i discover that there is no activities on ICP and HTCP, why? What is the implication of this? If they are important to squid performance, how can i implement them? Regards, Yomi Microsoft Windows [Version 6.1.7601] Copyright (c) 2009 Microsoft Corporation. All rights reserved.
