Use action from controller to return data to AJAX or load views with content?

Most Javascript frameworks implement that header as a psuedo-standard. It should be fairly reliable, but obviously testing and verification are important for developers. You could even use your own custom header name/value pair to "validate" the request (this is not enough for actual validation, but it works the same as is_ajax_request()).
