How to force Wordpress admin/login pages with SSL?

Question

I have WordPress in a sub-domain like blog.my-site.com and can't use SSL with sub-domains (https:// blog.my-site.com)

Is there a way to force WordPress admin/login pages ONLY to SSL URL https:// www.my-site.com/blog_dir/wp-admin/ (the folder name is not the same as sub-domain)

Answer 1

To force administration and logins over SSL, the proper way is to set the FORCE_SSL_ADMIN constant in wp-config.php.

define( 'FORCE_SSL_ADMIN', true );
