BodyRefreshLoadsJPU:refresh is a new navigation method

[tested]
Browser Ver
{ 
MS Internet Explorer: 6.0.2600.0000.xpclnt_qfe.021108-2107;
Encryption: 128-bit;
Patch:; Q810847; 
}
(So, it's far from fully patched. It also works after
applying the patch for method caching attack.) 
OS Ver: "Windows XP Cn ver"

[demo]
http://www.safecenter.net/liudieyu/BodyRefreshLoadsJPU/BodyRefreshLoadsJPU-MyPage.HTM
or
http://umbrella.mx.tc 
---> BodyRefreshLoadsJPU section
---> BodyRefreshLoadsJPU-MyPage file

[exp]
[VictimWindow] is in another security zone, execute:
[VictimWindow].location.href="javascript:[JpuScript]"
then [VictimWindow] will be navigated to a RES-protocol
page.
at last, press "REFRESH" button:
"Refresh" tries to reload "javascript:[JpuScript]", and
the script is executed.

question:how to press "REFRESH" button with JSCRIPT?
answer in this attack:
SaveRef(or "object-caching attack") "document.body", 
then:
bodyRef.document.execCommand("Refresh")

[how]
special thanks to:
"Andreas Sandblad" for "Using the backbutton in IE is
dangerous";
(then i tried to search for other navigation methods) 
"GreyMagic" for "GreyMagic Security Advisory GM#012-IE"
(it showed "[DocElement].document" is something
interesting :-) ) 
and myself :-)
read those documents. and look for buttons in MSIE.

[greetings]
the Pull, dror, guninski, sandblad, greymagic and
"Friedrich L.Bauer".
of course, mom and dad.

best wishes
