serviceworker will not work on http sites on Chrome

The error is:

Error: Service worker registration failed: SecurityError: Only secure origins are allowed (see: https://goo.gl/Y0ZkNV).

where the shortened link resolves to: https://www.chromium.org/Home/chromium-security/prefer-secure-origins-for-powerful-new-features

For example, Chrome is going to make Service Workers available only to secure origins, because it provides the origin with a new, higher degree of control over a user’s interactions with the origin over an extended period of time, and because it gives the origin some control over the user’s device as a background task.

So I decided the easiest way to answer this was with code - #128 😉

[psiinon]

The current plan is:

For HTML content requested by chrome/jxbrowser over http when the HUD is active:

• Redirect the browser to HTTPS (using https://developer.mozilla.org/en-US/docs/Web/HTML/Element/meta ?)
• Detect https failures and flag the domain (so we dont keep requesting https content)
• For all flagged domains, request the contents via http and fake the https response
• Provide some popup or other visual clue to explain what we’re doing to the user

Thoughts anyone?
