Re: [squid-users] Reverse Proxy Redirector Help

Joe,
you are not allowed to use echo statements that write to stdout because
Squid is expecting ONE line and one line only per line that the script reads.
In case of an error Squid gets a second line from the script and issues an
'I do not expect this' error.

the "exit" is also not very nice. Squid will complain about
a redirector that died and immediately start a new one.

BTW: ufdbGuard is a free redirector that can log all requests.
