One more may be last thing: - I found the strange behavior - if I make
changes at my ext ACL script (its python ) and then "squid -k
reconfigure" then I can see that my script appears in the "TOP" of
process and loads CPU to 100%
Check how your ACL script reacts to stdin closure/EOF. The script should
quit but probably does not. Same for any stdin reading errors. On EOF,
the script should use exit code zero. All these things are easy to test
on the command line (without Squid).

This part of the instructions were missed:

"
For every line sent by Squid exactly one line is expected back. Some
script language such as perl and python need to be careful about the
number of newlines in their output.
"
If your helper received something like this (with concurrency
channel-id
"1"):
"1 bob 192.0.2.1"
It should produce a line like:
"1 OK proxy=all"
If no concurrency channel-id is received, then output is the same but
without sending channel-id back and MUST be sent in same order as
received.
I do recommend using concurrency. It can help further debug issues with
helpers responding incorrectly.
