Issue looking up http links from https site

[elicwhite]

There is an issue when we are on an https site and try to make a request to load the content from a site on http. We can't make this request with javascript in the browser.

From what I understand this can be fixed by making the request in the chrome extension itself. We would then have to postmessage from the frame to the extension the URL we need, and then postmessage back to the frame the response.
