I want to move a client if she didn't pass my url authentication. e.g. ``` <mount> <mount-name>/mount</mount-name> <authentication type="url"> <option name="mount_add" value="http://some/url"/> <option name="mount_remove" value="http://some/url"/> <option name="listener_add" value="http://some/url"/> <option name="listener_remove" value="http://some/url"/> <option name="auth_header" value="icecast-auth-user: 1"/> </authentication> <!-- 1st example. Moving to other mount --> <on-authentication-failure>/othermount</on-authentication-failure> <!-- 2nd example. Playing pre-recorded file --> <on-authentication-failure>/sorry.ogg</on-authentication-failure> <!-- 3rd example. Firstplaying pre-recorded file, then play the stream anyway (or move to other mount) --> <on-authentication-failure>sorry.ogg+/othermount</on-authentication-failure> </mount> ``` Especially the 3rd example looks difficult, but I'd say it's a legitimate use-case to tell the listener that she didn't authenticate properly and is now getting e.g. a lower quality stream.
