I got a small site which served by Apache (I can't put Nginx in front nor change Apache to anything), and it is set up to serve the same site both over http and https (no redirects http->https is there so far, so both http and https versions are served in parallel).
What I need is to set up
.htaccess so the same URI via http and via https to serve different text file?
http://example.com/proto.txt says "The site is over http" while
https://example.com/proto.txt would say "The site served over https".
