abstract fun getAuthCredentials(isProxy: Boolean, host: String, port: Int, realm: String, scheme: String, callback: CefAuthCallback): Boolean
Called on the IO thread when the browser needs credentials from the user. |isProxy| indicates whether the host is a proxy server. |host| contains the hostname and |port| contains the port number.

This method will only be called for requests initiated from the browser process.
