Problem with admin/https and frontend/http

[hansglyk]

Hi! with https backend/admin and http website frontend, itis not possible to logout. you stay in backend until the end of time.

rename-wp-login - setup url: /mylogin

wp-config.php: define('FORCE_SSL_ADMIN', true); // ADMIN > SSL

,htaccess:

HTTPS - site running on port 443 or else (http over ssl)

RewriteCond %{SERVER_PORT} !^80$ RewriteRule !^wp-admin|wp-login|wp-register|wp-content|wp-includes|mylogin(.) - [C] RewriteRule ^(.)$ http://%{SERVER_NAME}/$0 [L]

Logout Link: http://www.mysite.de/?action=logout&_wpnonce=9e635e1d23

Èverything else works fine. How to fix that Https/Logout Problem?
