[squid-users] cache manager access from web

I have followed the tutorial here: http://wiki.squid-cache.org/SquidFaq/CacheManager
and set up acls to access the cache manager cgi on my server. I have to access this externally for the moment as that is the only access to the server that I have (SSH or web).
The cache manager login appears when I access: http://myexternalipaddress/cgi-bin/cachemgr.cgi
I have set the cache manager login and password in the squid.conf
# TAG: cache_mgr
# Email-address of local cache manager who will receive
# mail if the cache dies. The default is "root".
#
#Default:
# cache_mgr root
cache_mgr aaa_at_aaa.com
cachemgr_passwd aaa all
#Recommended minimum configuration:
acl all src 0.0.0.0/0.0.0.0
acl manager proto cache_object
acl localhost src 127.0.0.1/255.255.255.255
acl cacheadmin src 88.xxx.xxx.xx9/255.255.255.255 #external IP address?
acl to_localhost dst 127.0.0.0/8
# Only allow cachemgr access from localhost
http_access allow ncsa_users
http_access allow manager localhost
http_access allow manager cacheadmin
http_access deny manager

However, whenever I enter the password and select localhost port 8080 from the cgi script I get:
The following error was encountered:
Cache Access Denied.
Sorry, you are not currently allowed to request:
cache_object://localhost/
from this cache until you have authenticated yourself.
