Dizze plugin **is net hifke mei de lêste 3 grutte releases fan WordPress** . It 
kin net langer wurde ûnderhâlden of stipe en kin kompatibiliteitsproblemen hawwe
as it wurdt brûkt mei resinte ferzjes fan WordPress.

## Beskriuwing

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-login.php` or `https://example.org/
wp-admin/` the user is redirected to `https://example.seravo.com/wp-login.php` or`
https://example.seravo.com/wp-admin/`.

This plugin works with both normal WordPress installations and WordPress Network
installation and is compatible with the WordPress MU Domain Mapping plugin.

The code is optimized to be fast and does not for example do any database lookups
or use cookies.

This plugin is made by [Seravo Oy](https://seravo.com/), which specializes in open
source support services and among others is the only company in Finland to provide
[WordPress Premium Hosting](https://seravo.com/).

## Ynstallaasje

 1. Upload plugin to the `/wp-content/plugins/` directory.
 2. Activate the plugin through the “Plugins” menu in WordPress.
 3. Make sure the `wp-config.php` defines the needed constants.

Example:

    ```
    define('FORCE_SSL_ADMIN', true);
    define('HTTPS_DOMAIN_ALIAS', 'example.org');
    ```

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

 * http://example.com
 * https://example.com <- the case where https fails and we want to avoid
 * http://example.example.org
 * https://example.example.org <- the case where https works

## FAQ

### 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?

See https://codex.wordpress.org/Administration_Over_SSL

Note that defining FORCE_SSL_LOGIN is not needed.

### 󠀁[Works as expected](https://wordpress.org/support/topic/works-as-expected-542/)󠁿

 [Seravo.com](https://profiles.wordpress.org/seravo/) 7 April, 2020

Crude and simple, but works well. Not that relevant to day as Let's Encrypt and 
Certbot came along though.
