[Fiware-tech-help] Issue with XML3D and external URLs

[Philipp Slusallek]

Hi,

This is due to the security measures built in to WebGL. A Web site has
to explicitly allow its content to be accessible from other sites.
Otherwise it will be blocked. You need to configure your Web server to
include the relevant headers in the HTTP response
(Access-Control-Allow-Origin: *). For details please search Google for
"WebGL" and "CORS".

This should already be docuemnted for XML3D, btw.

Hope this helps. Let us know if you need more help here.


Best,

	Philipp
