Yes the http_access rule is the following :
http_access allow InternetAdmin

I also tested this option (with the sale result) I even removed the InternetAdmin line (still the same result)

I don't think there is any possible missmatch with those regex
(I used "http://download.tuxfamily.org/notepadplus/5.9/npp.5.9.Installer.exe"; to test a non-whitelisted url)

cat /etc/squid3/etc/whitelist.no_limit
www.microsoft.com
cdimage.debian.org

>Alternatively if you added the whitelist to http_access as well it could have screwed with the http_access login lookup. Making login unavailable and always fail at the delay_access check.

Most of the url in the whitelist.no_limit are also whitelisted somewhere in a http_access.
