Description
“HTTPS Upgrades” is a proposal to standardize opportunistic upgrades of idempotent main frame navigation requests to HTTPS with fallback to HTTP on failure. We’ve written an explainer and have opened a proposal issue and PR on the Fetch spec for how we think we could add this to the spec.
The ChromeStatus entry for this feature is https://chromestatus.com/feature/6056181032812544. We currently have a prototype implementation enabled in Chrome’s pre-release channels (Canary/Dev/Beta).
