So, I can do this all with one squid service listening on different ports? Out of interest, I had a post the other day: "proxy external ip address acl" You mentioned that adding an extra authentication would mess with the existing ncsa auth. Can I therefore add a 2nd authentication method on a different port and have 2 authentication methods running at the same time?
