h1. Tracker example

[[Tracker Example#Example-1|Example 1]] Shows how to create a basic public tracker which tracks every torrent which it sees in an announce request

[[Tracker Example#Example-2|Example 2]] Shows how to create a private tracker which only tracks torrents explicitly registered with it

h2. Example 1

<pre><code class="java">

        public void StartTracker ()

        {

            Tracker tracker = new Tracker();

            // When unregistered torrents are allowed, if a client requests peers for

            // a torrent which is not currently monitored by the tracker, that torrent

            // will be added automatically. This is useful for creating a 'public' tracker.

            // Normally, if this is false, announce requests for torrents not already

            // registered with the engine are sent an error message.

            tracker.AllowUnregisteredTorrents = true;

            // Set the interval between announce requests to 1 hour and min interval to 10 mins

            tracker.AnnounceInterval = TimeSpan.FromHours(1);

            tracker.MinAnnounceInterval = TimeSpan.FromMinutes(10);

            // Create a listener which will respond to scrape/announce requests

            // You can pass a prefix like: http://153.462.23.1/announce which will

            // create a listener on port 80 (the default HTTP port) which will handle

            // all announce requests.

            HttpListener listener = new HttpListener("http://myserver.com/announce");

            tracker.RegisterListener(listener);

            listener.Start();

        }

h2. Example 2

<pre><code class="java">

         // torrentDirectory is a folder containing .torrent files

        // which should be loaded into the engine

        public void StartTracker(string torrentDirectory)

            // Create the tracker and register a listener as in Example 1

            Tracker tracker = new Tracker();

            HttpListener listener = new HttpListener("http://myserver.com/announce");

            tracker.RegisterListener(listener);

            listener.Start();

            // If an announce request is received for a torrent which is not registered with the

            //the tracker an error will be returned.

            tracker.AllowUnregisteredTorrents = false;

            // Load all torrents into the engine. Only announce requests for these torrents

            // (or torrents added in the future) will be processed.

            foreach (string file in Directory.GetFiles(torrentDirectory))

            {

                Torrent torrent = Torrent.Load(file);

                // InfoHashTrackable is a basic subclass of ITrackable. It only stores

                // the infohash and name of the torrent. If you need to store additional

                // data for each torrent you're tracking, just subclass ITrackable or

                // InfoHashTrackable and add the extra data there.

                tracker.Add(trackable);
