The downloading and launching of BlueZone emulation client sessions is accomplished via the BlueZone Web-to-Host control module,
which is downloaded and then installed in the user's browser. The Web-to-Host control module controls the downloading and
updating of BlueZone files from the web server to the user's machine.
There are two versions of the Web-to-Host control module: an ActiveX control version and a Java Applet version. The reason
for two is that only Internet Explorer supports ActiveX. All other browsers like Netscape, Mozilla, and Opera, support Java.
