How would a relative href link look that should only change the protocol of the current URL?

Assuming I am on

http://sub.example.org/path/index.htm

How would a 

<a href="">Link</a>

line look if all it should do is changing the protocol to https:

https://sub.example.org/path/index.htm

without needing to know the current URL where the page is located (sub.example.org/path/index.htm), so being relative?

Example use case: Provide a "Use secure connection (HTTPS/TLS) from now!" link on all pages.

You cannot achieve this using relative URIs. A relative URI will always start at some point and then change everything to the right of that point.

You can calculate the URL using server side code or JavaScript:

location = location.toString().replace(/^http:/, "https:");
