w3c validation congratulation ICON code results broken link

I have checked one of our sites (http://www.pantilimon.ro) in w3c validato开发者_如何学Pythonr, and took the congratulation icon HTML code, inserted into my code, but it contains two broken links: http://validator.w3.org/check?uri=referer and http://jigsaw.w3.org/css-validator/check/referer

what to do now?

They're not broken here. Could it be that you have some sort of firewall or proxy that removes the Referer request header?

The links you have posted use the HTTP_REFERER header - that is, the URI of the page that you came from.

Use the actual URI.
