+	@capability:  page autorefresh
+	@discussion: I know of 3 ways to get a page to reload, 2 of those ways are pretty much the same
+	(1) the http header 
+		Refresh: 5;
+	(2) the META http-equiv 
+		<META HTTP-EQUIV="Refresh" CONTENT="5">
+	both 1 and 2 have the same effect as hitting the "reload" button, which in *many* browsers will
+	force a re-download of all the images on the page, i.e. the browser will NOT use the cached images
+	(3) java script combo of "window.setTimeout" with "window.location"
+		window.setTimeout('window.location="http://example.com/phpgw/email/index.php"; ',1800000);
+	method 3 is the only one I know of that will use the images from the cache.
+	also, 3 takes a reload value in miliseconds, so a value of 180000 is really 3 minutes
+	ALSO, use if..then code to only auto-refresh certain pages, such as email/index.php
