Does not work with http sites anymore

[Hugh Jeffner]

I was using this for years on a locally-hosted http site and recently I started getting the 'white screen'

Testing revealed that it seems to still work for https sites but not http, most likely a security 'feature' introduced by a chromecast update. Since the site is not accessible to the public free TLS certificates are not an option and self-signed certificates are obviously out of the question.

As a work-around I switched to using the loc method instead of iframe and it works fine.
