When the client sends a request to the server, if an extra conf file is found that is not already white/blacklisted, the server stops processing the request and tells the client that an unknown extra conf file has been found. The client then asks the user if that file should be loaded or not. Depending on the user's answer, the client sends a request to the server to load or ignore the extra conf file. Finally, the server loads the file or adds it to the blacklist. However, the initial request was not processed by the server and should be sent again.
