[squid-users] Squid 3.5 ICAP Problems

[Stephen Stark]

Hello,
I found put my problem.

c-icap service was running fine.
I had a modification on FwdState.cc that was not handling any localhost
request. So it squid could not resolve host.

Thanks for the help! It helped me find where the problem was using debug
options ALL,9.

You can turn detailed debugging on when the problem re-appears. Search
Squid wiki for "-k debug" for a related discussion and advice.

However, for performance issues, it is best to try to isolate the
bottleneck _before_ slowing down Squid with detailed debugging. That is
difficult to do and there are no scripted actions to follow, but you can
start by logging (access.log and icap.log) various response times and
the number of open connections (/proc/ or netstat -n) to narrow down
suspects.


HTH,

Alex.
