将特定文件夹重定向到HTTPS和Wordpress

Question

I know this question was asked so many times on SO, and I found all the relevant answers to my post, but my situation is a bit more unique, therefore I couldn't use the given answers as solution for my problem.

I have a website http://www.example.com which has a folder with the name: secure. When a user tries to go to http://www.example.com/secure , he should be redirected to the HTTPS version of the site. Now for the tricky part - on the secure page there is only HTTPS links, as requested by every SSL certificate. specifically there is a link to https://www.example.com - but when a user clicks it, he should be redirected to the HTTP version of the site. as mentioned - the main page is not secure.

I figured I would need two Rewrite rules:

1. Redirecting everyone trying to get to http://www.example.com/secure to HTTPS protocol.
2. Redirecting everyone trying to get to https://www.example.com to HTTP protocol.

This is what i have now in .htaccess in the root directory of the domain based on another question I found here.

RewriteEngine On
RewriteBase /

# Turn SSL on for /secure
RewriteCond %{HTTPS} off
RewriteCond %{REQUEST_URI} ^/secure
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]

# Turn SSL off everything but /secure
RewriteCond %{HTTPS} on
RewriteCond %{REQUEST_URI} !^/secure
RewriteRule ^(.*)$ http://%{HTTP_HOST}/$1 [R=301,L]

This works fine for redirecting the secure page to HTTPS, but I can't figure out why it's not redirecting https://www.example.com to HTTP.

Also worth mentioning, I have the following code in the same .htaccess that I can't remove.

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

Try your rules based on THE_REQUEST variable instead of REQUEST_URI . THE_REQUEST variable represents original request received by Apache from your browser and it doesn't get overwritten after execution of some rewrite rules , unlike REQUEST_URI variable.

RewriteEngine On
RewriteBase /

# Turn SSL on for /secure
RewriteCond %{HTTPS} off
RewriteCond %{THE_REQUEST} /secure [NC]
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L,NE]

# Turn SSL off everything but /secure
RewriteCond %{HTTPS} on
RewriteCond %{THE_REQUEST} !/secure [NC]
RewriteRule ^ http://%{HTTP_HOST}%{REQUEST_URI} [R=301,L,NE]

Also better to test this in a new browser after clearing browser cache.
