Resend request when extra conf is loaded or ignored
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.
