https://x3dgraphics.com/examples/X3dForWebAuthors/Chapter09EventUtilitiesScripting/BooleanSequencerIntegerSequencerCobweb.html

shows these errors on the console:

Blocked loading mixed active content “
http://cdn.rawgit.com/create3000/cobweb/master/cobweb.js/fonts/DroidSerif-Regular.ttf”[Learn
More]

This to me looks more like it is related to internal cobweb font loading.
Perhaps it is already fixed with the latest x-cite ?


Currently am using form recommended by Cobweb, i.e.

To me that looks good. There is also a way to use the default protocol by
using a protocol relative url:
src="//cdn.rawgit.com/create3000/cobweb/master/stable/latest/cobweb.min.js
<https://cdn.rawgit.com/create3000/cobweb/master/stable/latest/cobweb.min.js>
"

Holger would need to chime in since it looks to me it may be a cobweb issue.

Fraunhofer started offering https delivery of x3dom which would be normally
preferred. Protocol relative URLs may work best since people may access
examples using either protocol.

I guess, using the event utility nodes just leads to somewhat verbose
scenes which at first looks distracting but is not really a disadvantage
(although large web sites would care int terms of bandwidth).
