You can connect to a remote service, or use GUI to simulate it.<br /><br />To intercept or manipulate data you can use various features:<br /><br /><strong>RegExp Block</strong> stops the automatic forwarding of matched messages. When a message is blocked you can modify it before passing it.<br /><br /><strong>RegExp Replace</strong> automatically modifies data stream according to the configured regular expressions.<br /><br />We tried to make PassiveNetwork as intuitive as possible: <em>feel free to experiment with the various features</em>! ;)");
