Hi, I want to block the css visualization in my .htaccess file but allow users to view my validation status. I've tried to put w3.org or http://jigsaw.w3.org in the allowed http_referer but it doesn't work. What kind of http_referer can I use? I think the validator use one script on another domain for the validation service.
Sorry for my bad english.
