Using SSL (https) with served libraries / CDN

What do you all think of using CDNs such as what cloudfare provides.

for example this line could be in your agent code if you are doing the Agent hosted / self-hosted website

<script src=""//""></script>

I tested this line and it appears to load without errors. I did not actually build a chart but I guess it would work.

I previously thought that Highcharts was not available via SSL but then I found this. I am a bit confused about the economics of it. Why does cloudfare provide this service? Is it legit and safe?

It looks like D3.js is also available there.

Good find. Here’s a piece by TNW on Cloudflare… seems like they became a CDN by accident.

This is a good find here’s the full list of all the javascript libraries they hold
