Force saving a lowercase URL in the SilverStripe admin

Question

For SEO purposes I need to be sure all URLs are saved as lowercase.

How can I force the SilverStripe admin to save the URL in lowercase even if the user types the permalink in uppercase?

You can do this in your Page's onBeforeWrite method:

protected function onBeforeWrite() {
    parent::onBeforeWrite(); //this is important!
    $this->URLSegment = strtolower($this->URLSegment);
}
