I have some Idea about transparent proxy with authentication but I don�t sure it makes sense or not, may be some one can craft this.
I�m using backbone switch to route HTTP request to transparent squid and it works fine. I know that no way (by now) to automatically pop up authen screen for routed users while I�m using transparent proxy. But suppose I have some firewall box or some thing that do firewalling routing and Authentication placed between backbone and proxy then set the policy says �whoever want to access the proxy server need to be authen on this URL first�. Is this the possible solution ? and if it ,which software or firewall can do that especially open source :)
