Dear developer, I'm using the squid-3.HEAD-20080811, and trying to deliver icap connections properly as I expected. It means to activate icap or not by using adaptation_access with ACL. However, adaptation_access didn't seem worked properly. I configured ICAP settings as below. acl eicar url_regex http://www.eicar.org/ acl trend url_regex http://www.trendmicro.co.jp/ icap_service service_1 respmod_precache 0 icap://192.168.10.231:1344/interscan icap_service service_2 respmod_precache 0 icap://192.168.10.232:1344/interscan adaptation_service_set svcBlocker service_1 service_2 adaptation_access svcBlocker deny eicar adaptation_access svcBlocker deny trend #adaptation_access svcBlocker allow all --> commented In this case, squid did activate both eicar and trend, and then connected to the ICAP server. I'm wondering, if adaptation_access has lack of software, or my configuration is something wrong? Best Regards, Seiji Kobayashi
