Force https to http redirect except for WordPress /wp-admin directory

First move all requests that are not wp-admin requests from https to http.

Than i want to exclude all of WordPress admin from the https to http redirect, to keep WordPress admin working over https, so this is the result:

RewriteEngine On

RewriteBase / 
RewriteCond %{HTTPS} off 
RewriteCond %{REQUEST_URI} ^/?(wp-admin/|wp-login\.php) 
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L] 

RewriteCond %{HTTPS} on 
RewriteCond %{REQUEST_URI} !^/?(wp-admin/|wp-login\.php) 
RewriteRule ^(.*)$ http://%{HTTP_HOST}/$1 [R=301,L]
