[squid-users] ICAP Bypassing Causing Performance Issues

Hi,

We have had to put in a number of URLs to the squid bypass

icap_service service_1 reqmod_precache 0 icap://127.0.0.1:1344/reqmod
icap_class class_1 service_1

acl bypassIcapRequestURLregex urlpath_regex "./squid-3/etc/byPass_ICAP_request_URLregex.properties"
icap_access class_1 deny bypassIcapRequestURLregex

When we added 4 regular expressions to this file, we started to see the CPU usage going up quite a bit, and we started to see the number of established connections from squid to ICAP server double or triple.

Is this a known issue? Is there a better/more efficient way to bypass ICAP than above?

Regular expressions were very simple, just matching end of URLs.

We're running squid 3.0.15 on Solaris 10.

Thanks and regards,
Justin
