I have an issue with my browser and squid where they both seem to be stuck in
an infinite loop of denied requests.
I have a a helper script that authenticates the user. The script works. Here is
an example of the output of authentication
being successful and not successful.
[root@1 ~]# /etc/squid/authenticate.php
test1 test1
OK
test1 test2
ERR login failure
So, I am sending the right info back to squid. When I authenticate successfully
then squid and my browser play nice and there is no power struggle.
If the authentication fails then I get this:

Here is my squid config:
#
# Recommended minimum configuration:
#
# Example rule allowing access from your local networks.
# Adapt to list your (internal) IP networks from where browsing
# should be allowed

Everything I’ve read and tried always left me with the same result which was an
infinite loop rather than squid returning an unauthorized result page.
Any help would be greatly appreciated.
