</ul>

<p>This plugin enables WordPress to send HSTS header to browser</p>
<p>IMPORTANT NOTE: This plugin won’t work if you use any WordPress caching plugin. If this is the case, then update your .htaccess file to specify HSTS header.</p>
<p>HTTP Strict Transport Security (HSTS) is a web security policy mechanism that helps to protect websites against protocol downgrade attacks and cookie hijacking.</p>
<p>It allows web servers to declare that web browsers (or other complying user agents) should interact with it using only secure HTTPS connections, and never via the insecure HTTP protocol</p>
