Accepted answer

it seems many proxy servers admins don't allow compressed javascript modules:

so it would be nice if the highcharts cdn didn't force compression. until that changes the best i can suggest is try to load from highcharts cdn, fallback to your own server if that fails. perhaps like this;

<script src="//"></script>
<script>!window.highcharts && document.write(unescape('%3cscript src="../js/highstock/highstock.js"%3e%3c/script%3e'))</script>
<script src="//"></script>
<script>! && document.write(unescape('%3cscript src="../js/highstock/modules/exporting.js"%3e%3c/script%3e'))</script>


for the highcharts library this problem can be solved by using a different cdn such as:


unfortunately, the highstock library isn't held on cdnjs, or any other cdn that supports uncompressed download (as of apr 2013).
