[Zope] multiple visits to dtml-method page

[Sam Gendler]

IE will show a cached page, regardless of the settings, when hitting the back button.
If you were to type in the URL, it might actually get the page, but you can never be
too sure with IE.  Its cache is terribly misbehaved.  Try making the page uncacheable
with a Cache-Control: no-cache header.  To verify if this is the problem, hit
ctl-reload in IE (shift-reload in netscape) to force a reload of the page.
