[squid-users] Could not connect to ICAP server

Hello there,

recently, I experience a lot of problems with the ICAP patch. From time
to time, clients receive the Squid error page telling that ICAP is
unavailable. The ICAP server is ISS Proventia Web Filter.

Here is what the log file says:

Any idea what could be wrong? The ICAP server is on the same machine as
Squid is, so network connectivity problems cannot be the cause.
