To make sure you are not storing a version in the browser cache use the ctrl
+ F5 (IE, I don't know what the NN equivalent is) to reload the page.  ctrl
+ F5 will cause the browser to request a version of the page from the server
(not serve up the page from the browser cache - which is done if the
timing/caching paramaters in the page header indicate that the page has not
expired).

You can also try embedding timing/caching parameters in the page header:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<meta http-equiv="Content-Language" content="en-ca">
<meta http-equiv="expires" content="Sat, 01 Jan 2001 00:00:00 GMT">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="pragma" content="no-cache">
</head>
