Amos, Thanks for your reply and help. Squid version as it is shown in the add/remove programs of Fedora 12 reads, "Squid-7:3.1.0.17." I assume that is version 3.1. SquidGuard is "Squid-1.4-8.fc12." I am trying to follow the instructions of Alex Vanherwijnen (link in original post) to create a captive portal. Everything seems fine except for the url_rewrite_program which crashes Squid. The advantage in using his solution is it maintains a database of user connections, so only one redirect will happen to the login page during the session time period. I did look at the two links you posted. The session helper looks like a better solution. The problem is this is all a new area for me and I'm not sure I can pull that off without some examples to look at. Do you know of any that are posted? A last thought. I wonder. Should I be trying to use Squid Guard for the captive portal? It would seem to somehow be involved in the redirect. The service is running, but I have not configured it in any way.
