Load JSON from Web and Cache it

Simple try to load JSON from an external URL. The Python SOP is animated, but with static non changing JSON data. To avoid a request on every frame change in the animated Python SOP, I've stored the data in a hou.expressionGlobals key.
This gives a difference from uncached 4 Frames to cached 120++ Frames per second. I know that loading from an external Url is very time consuming, but maybe it helps at loading local files, too.
I don't know if this is the right way to store data Frame independent, but it's working :-)
