This is the way the validator recognizes the addresses from which it was “called” so that it knows which page should be validated. Normally browsers send a Referer header when you follow a link. Your browser might have been configured not to do so, as a privacy measure, or maybe a proxy used by your organization filters the header away. In any case, you cannot use the validator using that URL if the Referer header (with a value pointing to your page) is not present. You can use a different approach in a link, but then you need to hard-wire your URL (say http://www.example.com) there: http://jigsaw.w3.org/css-validator/validator?uri=http://www.example.com > Also referrer has 2 Rs: referrer.. The HTTP header name is “Referer” by definition, see http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.36 Yucca
