I may be showing my ignorance here (see 
http://www.swiftys.org.uk/wiz?574) but my sample JavaScript uses 
document.Lastmodified and I have no recollection of encountering 
currentScript.

However, when pressed on "do you know abut the document.lastModified 
property?" my answer would have to be "not much", as that was part of 
the original script that I cribbed (and have changed little). I know 
that it returns the date that the HTML was last changed, and that this 
information is passed from server to browser in the HTTP headers. The 
mechanism seems fully robust, and very widely supported. However, I 
can't imagine anyone getting sufficient worked up to contact me when the 
phrase "This page was last updated" is followed by nothing (the result 
when the JavaScript fails on:
"DayOfWeek[(LastModifiedDate.getDay() + 1 )]"

I would perhaps use server-side to detect the changed-date of my 
index.html file on the various webservers where I operate, but I suspect 
this would require PHP to be activated on the servers. My 
http://www.swiftys.org.uk/index.html comes from a server where PHP is 
not activated, and the SysAdmin of the site did me a huge favour when I 
requested certain features, so I try not to rock  the boat by asking for 
more.

It's a good idea to generate the "This document last changed [date]" in 
the CGI scripts, where possible, and I will enjoy implementing this 
change. I suspect my CGI scripts would not generate the necessary HTTP 
header for document.lastModified to work, anyway.
