Preventing the use of the browser's "Back" button

Overview

If the browser "Back" button is used to display the previous page, this action will have no effect.

Operating mode

Disabling the "Previous page" feature of the browser inserts the following JavaScript code into the generated HTML page:

<SCRIPT LANGUAGE="JavaScript">
history.forward()
</SCRIPT>

When running the page in a browser, it will not be possible to go back to this page by using the "Back" button.

Remarks

This action will have no effect.
Clicking the browser "Back" button can make the page blink.
This mechanism can fail if the browser [STOP] button is clicked before the forward() statement is run by the browser.
