 /**
  * Ensure the current connection with the user agent is secure with HTTPS.
  *
  * This function uses {@link isHttps()} to determine whether the connection
  * is via HTTPS.  If it is, this function will return successfully.
  *
  * If it is not, what happens next is determined by the following steps.
  *
  * 1. If $allow_override is true and allow_plaintext is also true,
  * then the function will return successfully
  * 2. Otherwise, then it will either redirect (if $action is
  * redirect) or return an error (if $action is error)
  *
  * @param string $action what to do if connection is not secure - either
  * 'redirect' or 'error'
  * @param boolean $allow_override whether allow_plaintext is checked
  * to see if an unencrypted connection is allowed
  * @param string $redirect_url if $action is redirect, what URL to redirect to.
  * If null, this will redirect to the same page (albeit with an HTTPS connection)
  * @param boolean $strict whether HTTP Strict Transport Security is active
