Hi Guillermo,

Try putting these host entries:
127.0.0.1 localhost
127.0.0.1 alaskaair.com
127.0.0.1 test.alaskaair.com
127.0.0.1 archtst1.test.alaskaair.com
127.0.0.1 push.alaskaair.com

If it helps, this was what I had:

127.0.0.1 local.mysite.com
127.0.0.1 local.www.mysite.com
127.0.0.1 lightstreamer.mysite.com
127.0.0.1 lightstreamer.www.mysite.com

And the javascript was set up like this:

var page = new PushPage();
page.context.setDomain("mysite.com"); //for you, try: alaskaair.com

//create the engine
page.onEngineCreation = function(engine) {
engine.context.setDebugAlertsOnClientError(true);
engine.connection.setLSHost("lightstreamer.mysite.com"); //for your case try: push.alaskaair.com
engine.connection.setLSPort(8090); //for your case 8080
engine.connection.setAdapterName("MyAdapter"); //change to your required adapter
engine.changeStatus("STREAMING");
}
page.bind();
page.createEngine("MyApp", "http://local.www.mysite.com/LS", "SHARE_SESSION"); //for your case, http://archtst1.test.alaskaair.com/JSLib or move the JS files to http://archtst1.test.alaskaair.com/LS

Hope that helps!
