Force http to one filder rest force https - .htaccess

Question

I am trying to force non-https to only one folder on the site but the rest all should be https. Here is my .htaccess code:
RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]
RewriteRule ^reports$ http://%1/$1 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([0-9a-zA-Z].+)$ /page.php?title=$1 [L]
ErrorDocument 404 404.php

I guess the problem you have is, that even the reports-folder gets forced to https. Is that right?
That would be, because you put that rule first. The general rule order should be: Most specific first, most general last. So your general https enforcing rule should be last. Or at least it must be after your http enforce rule.
Also you only force /reports/ to http. Everything in that directory would be https again. I think you should change it to
RewriteCond %{REQUEST_URI} ^/reports/(.*)$ [NC]
RewriteRule ^(.*)$ http://yourdomain.com/$1 [R=301,L]
If I see it correctly, you enforce everything to not start with www. Put that rule after the reports-http rule and change it to https. This will save you one redirect.
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ https://%1/$1 [R=301,L]
Than your https-enforce rule and than the rewrite to page.php if not existing file or directory.
