One of the great features of a Flash Projector file is that it loads movies and variables not only from your hard drive, but also from the web. When you need to talk to a web server to retrieve or update data, Flash has the ability to use the GET and POST command to update data on websites. But if users are not connected online then the data will not be sent or retrieved. Uh-oh. This is why we created JNetCheck. With this JTool, you can check to see if the user is online or not, all from one simple command.
