The default MathJax configuration uses the CDN version of MathJax, but MathJax can be installed locally if required.

This can be useful to save on bandwidth or because of local proxy restrictions.

To use a local installation of MathJax, first download the full MathJax library from http://www.mathjax.org/. Then install it on a web server. Finally update the MathJax filter settings httpurl and/or httpsurl to point to the local MathJax.js URL.
