This plugin is useful e.g. if you have a wildcard SSL/TLS certificate for server but not for each site.
If the site is normally at say
http://example.org/ and you want to have the admin area https protected, but you don’t have a SSL/TLS certificate so that
https://example.org/ would work, you can define another domain for secure connections.
For example instead of
https://example.org/wp-admin/ the user is redirected to
This plugin works with both normal WordPress installations and WordPress Network installation and is compatible with the WordPress MU Domain Mapping plugin.

The plugin scenario assumes the site domain is example.com but there is no https certificate for it. Instead there is a https certificate for example.org, which has been defined as the HTTPS_DOMAIN_ALIAS.
In a WordPress Network installation the HTTPS_DOMAIN_ALIAS can be defined as *.example.org and then <domain.tld> will be redirected to .example.org. This plugin is designed to be compatible with
the WordPress MU Domain Mapping plugin.
Possible values of $location when calling this function
- https://example.com <- the case where https fails and we want to avoid
- https://example.example.org <- the case where https works
Does this work for WordPress Network?
Yes, since version 0.4.
Where is the UI?
This plugin has no visible UI, the magic happens automatically if the plugin is active.
What does FORCE_SSL_ADMIN do?
Note that defining FORCE_SSL_LOGIN is not needed.
