Re: Error when attempting to access Referer

But maybe it could be possible to provide a more user friendly
message? 

	Not a plain / text-only version, but like the rest of the validators
sites maybe? 

	Including the explanation, you just gave to Samuel, would be nice
too. 

	I guess this could help some people...

	As the last part of the URL suggests, the URL is meant to be used in
a 

	situation where the HTTP headers contain a Referer header. 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) [2] there: 

	http://jigsaw.w3.org/css-validator/validator?uri=http://www.example.com

	The HTTP header name is “Referer” by definition, see 

	http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.36 [4]
