icecast-server/src/auth.h
Karl Heyes e6dfee632c Allow source client authentication via auth handler. Here the URL handler can
issue requests (using ithe stream_auth option) to allow external engines to
determine whether a client can stream or not. Admin requests using source auth
are able to use this mechanism however source clients using the icy protocol
cannot yet.
