Thanks for this Reinhard,

I agree, the env settings in my rules are just making a lot of noise. Your rules are much easier.
One problem I see is that your [2] seems to create an infinite loop. When a user go to http://localhost/myapp. This will infinitely trigger the rule over and over again.
What I have done is to add a RewrtiteCond before and it now the rules look like 

#[1] all /user, /subscription and /login pages should be served in https
RewriteRule /myapp/user https://%{HTTP_HOST}%{REQUEST_URI} [R,L]
RewriteRule /myapp/subscription https://%{HTTP_HOST}%{REQUEST_URI} [R,L]
RewriteRule /myapp/login https://%{HTTP_HOST}%{REQUEST_URI} [R,L]

#[2] For all other pages, if in https mode, serve the page in http mode.
RewriteCond %{SERVER_PORT} ^443$
RewriteRule .* http://%{HTTP_HOST}%{REQUEST_URI} [R,L]

The RewriteCond solves the problem of the indefinite loop, BUT still, the switch from https to http does not occur...

The following change solved the problem. ALSO, I had to put it in my <VitualHost *:443> section!!!

#[2] For all other pages, if in https mode, serve the page in http mode.
RewriteCond %{SERVER_PORT} ^443$
RewriteCond %{REQUEST_URI} !^/myapp(/login.*|/user.*|/subscription.*)
RewriteRule .* http://%{HTTP_HOST}%{REQUEST_URI} [L]

Thanks again for your inspiration
