Don't worry, sending to squid-users will get to me.

> Hello Amos and all readers, thanks for the speedy and informative reply. 2.7.STABLE6 will not configure with --enable-icap-client and 3.0.STABLE13 makes and installs OK but won't accept anything on the gateway. The squid.conf is default except for debug_options set to ALL,3. The error condition follows with a snippet from: cache.log. Please advise, David.

2.7 has no ICAP support. It was new in 3.0.

The error page you got was due to receiving non-proxied request (ie
intercepted, or reverse proxy request).

Since you say squid.conf is the default, then that is likely your
problem. Squid needs to be configured specially to handle unusual requests.

  see whichever of these apply to your intended situation:
