If you look at the article mentioned you'll see that it refers to a
bug in IE related to handling HTML <META HTTP-EQUIV> tags, which are
of course ignored by proxy caches [1]. They are so broken that no-one
should use them.

[1] Unlike most proxies, Cache-Flow boxen do parse HTML in order to
pre-fetch inline images, but I don't know whether they also pay
attention to <META HTTP-EQUIV>...
