Ed,
I didn't believe you when you mentioned the IFRAME, so I tried it. You were
right!
ASP.NET renders:
<IFRAME ID=__hifSmartNav NAME=__hifSmartNav STYLE=display:none
src="IEsmartnav1"></IFRAME>
right after the body tag. It also renders a script tag looking for
SmartNav.js. That's 9kb of complicated JavaScript, attaching handlers to the
form submit event and others. I'm not sure, but I think I may have caught it
actually moving my HTML into a new IFRAME! I wouldn't be shocked to find out
that it doesn't work.
I _would_ be shocked to find myself ever using it now that I see that I'd
have 9kb worth of somebody else's code to worry about in addition to my own.
Is that 9kb of script code documented anywhere? There's enough of it that it
damn well ought to be documented!

Yes, it is SmartNavigation -

us/cpref/html/frlrfSystemWebUIPageClassSmartNavigationTopi
c.asp
When you turn it on ASP.Net puts the content that is
going to be updated in iframes giving the appearance that
the page is updating without POSTing back. Haven't used
it myself, but apparently it's buggy.

Not entirely sure what it is but I have read mention of
a feature calledSmartNavigation that helps stop the page 'flashing' when
you reload/post.<%@ Page Language="vb" SmartNavigation=true
AutoEventWireup...etc.

SmartNavigation.aspx
Not sure if this is exactly what you were after though -
I haven't used ityet myself.
