Forgive me if there's already some way to do this, but I couldn't find anything.

I also considered that a workaround might be to use SavedVariables along with an external program for reading URLs/writing data to them, but it appears that the SavedVariables are only read when the add-on initially loads.

Anyway, it would be extremely useful for all kinds of reasons to be able to fetch data from a URL for an add-on to use. I totally get that there may be some good gameplay reasons not to allow this, but I think as far as raw security goes this is probably fairly safe (especially since add-ons are open source).
