To handle the caching problem, I've tried the following scheme. I've made an exact copy of the mathjax directory (mathjaxcopy) and pointed the footer (which loads MathJax) to the copy. Since the path to the file is different, I think your browser has to actually fetch the file. Of course, if you have the footer cached, that will have to refresh first.
Sorry about all the trouble. Thanks for the reports.

Is there some easy way to avoid this problem with future updates? Does anybody know how to tell Apache something like "if somebody fetches this file, tell them that this bunch of other files have changed"?
