Mismatch protocol http and https

Question

This issue occurs when the frame requesting access has a protocol of https, the frame being accessed has a protocol of http(toplevel, http://www.example.com/ particularly). how to get around this problem? Thanks for advance!

Answer 1

You could try to make it protocol agnostic if the frame supports either protocol. That way it'll choose the one being served.

Eg

<img src="//www.placehold.it/250x250" />
