You can achieve the same effect by using the HTTP "expires" header, with the
document expiration date set to the current time. This technique has the
additional advantage that proxy servers and the like can know not to cache
the document without having to parse HTML code. (Also, this attribute can
apply to file types other than HTML documents.)
