That's not a good idea. It's just not the way HTTP and browsers work. Every browser will open multiple connections and expect them to succeed. It won't use the first (successful) connection to load files that fail to download on a 2nd connection.

You should instead implement a login/logout/timeout procedure to limit configuration changes. However, that's not provided as a service by our webserver (yet?).
