SS loads a bunch of JS files at the end of my pages (Prototype, behaviour.js, i18n.js ...).

But I really don't need them on my page. It just cranks up download time for users. Where do I fix that?

In Page_Controller I use this for excluding prototype and thirdparty scripts, like userforms

	public function init() {
		parent::init();
		Requirements::block('sapphire/thirdparty/jquery/jquery.js');
		Requirements::block('userforms/thirdparty/jquery-validate/jquery.validate.min.js');
		Validator::set_javascript_validation_handler('none'); 
	}

patte, thanks for your help. You saved my users a lot of traffic :)

The search field wants to load lost of validation js. You can kill those in your _config file with the following line:

Validator::set_javascript_validation_handler('none');
