What you are attempting to do is get the browser to authenticate against the proxy by sending authentication details to a web server somewhere else. What you need instead is one of two captive portal solutions: 1) authenticate against the proxy directly, no fuss. http_access allow freesites http_access deny !AuthUsers http_access deny all 2) use an external_acl_type helper to perform side-band authentication based on IP using details gathered from the website login. external_acl_type foo ... acl AuthsUsers external foo http_access allow freesites http_access allow AuthUsers deny_info http://login.mydomain.local all http_access deny all (2) has cons in that it assumes you are able to create a working auth scheme where experts often fail. Also that every visitor has a unique IP/headers (no sharing, no NAT) and forgery is ignored. Amos
