BTW, the reason I *had* to figure out how to do this is because after
uploading a file, the server spits out a javascript redirect (this.replace ...)
to the folder url the uploaded to. If that page was cached, the user would see
the cached page instead of the new one with the new icon(s) for the
files they just uploaded.
