HTTPS usage among the web

The software we are currently working on, heavily depends on browser referrer policy. To make everything work properly, we need to know the whole referrer of the website using our app.

The worst thing is that, with all the privacy-related trends, browsers strictly restrict sharing full referrers by default, or even with the latest updates, just ignore protocol instructions.

Also, there are strict limitations on referrer policy when data exchange between sites occurs over http and https protocols. We have had a discussion about whether we should care about sites still using http or not.

I can barely remember the last time I visited an unsecured site. I tried to look over search results for a few high-frequency keywords and only found one site on six results pages. Also, the latest report I found states that 74.9% of total websites use https as a default.

Let Encrypt and Cloud Flare have done tremendous work to make the web a more secure place. The http-based sites might be ignored for now.
