i have a web-gw issue need your help. thanks.
McAfee Plugins for ISA 1.4
for issue :
now our web-gw running on proxy mode and enabled ICAP server feature. then installed the McAfee Plugins for ISA on ISA server as a ICAP client. let all the WEB traffic redirect to WEB-GW . it works well. we also enabled the "bypasss on failure" function on mcafee plugins. we let the web-gw down then all traffic back to original line. but we faced a issue that it came the below message when access the websites on client PC. i tested it on my lab, i can reproduced this issue . my customer do not want to show this on client pc when the web-gw down. May i know what is the root cause and how to fix it ?
please check my config from ISA as below, the ip address 172.16.80.233 is the web-gw and enabled the "bypass on failure" feature.
we let the web-gw down or disable ICAP server feature on web-gw. then the client pc keep accessed the websites fine and we can see all ICAP packet sent to WEB-GW failed. but the message is displayed on the website. if we disable reqmod and respmod on Plugins, then issue gone.
Please create a case, any information I would want from you may be sensative and I would not want you to post it here.
Please gather a tcpdump and a feedback from the Web Gateway.
Since all requests are in a failure state, I would guess that the ICAP server would be off on the MWG.
thanks for your help.
but i think this issue is not from the web-gw. as i pointed out as above that we make the web-gw down, then the client pc keep accessing website fine , that means the"bypass on failure" feature is working. but just raised the message on website page . if we disable ICAP client (disable reqmod and respmod on plugin) on ISA then the issue gone. (note: if the web-gw down, but enable ICAP client on plugin , so the all request are in a failure state that is in my expect. )
