<p>A simple WordPress plugin that redirects your site to HTTPS</p>
<h3>Simple SSL</h3>
<p>With Simple SSL you can enable HTTPS redirect for your website that is running on a Apache-based webserver.<br />
It is required to have a valid SSL certificate for your site that we do not provide.</p>
<h3>What does the plugin do?</h3>
<p>It configures your .htaccess file which is a configuration file used by Apache.<br />
We add the following setting that configures your website to redirect all traffic to HTTPS.</p>
<pre><code>RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301,NE]
</code></pre>
<p>We also automatically update your general settings to use HTTPS instead of HTTP.<br />
You can easily enable and disable all this from the admin page.</p>
