mv_no_cache tells minivend not to cache the page, this will not help with
browser cache and web proxy cache.

<meta http-equiv="Pragma" content="no-cache"> in the head of an html
document will work with most browsers and proxies, unless the tag is not
honored.

pretty much the safest way is to pass some more or less random number as a
variable, e.g. time. This should break almost any caching scheme.
