If your browser is vulnerable for this IE bug, then you will only see “The time is now xxx”, where xxx is the date and time. You will not see the “Something before the JavaScript” and also not the “and something after the JavaScript”.
Look at the source code (View > Source). You also will only see “The time is now xxx”, and you don’t see any JavaScript code.
Just hit the Refresh button, press the F5-button on your keyboard or press Ctrl+F5. The time will stay exactly the same, and will not be reloaded. This is to see that even IE6 itself has “forgot” the JavaScript code and only see the generated HTML code of the JavaScript, but not the JavaScript itself.
Just close your Internet Explorer 6 and restart it and surf to the same URL. The exploit will give you again the time, now updated, but you will not see again anything more.
