I include the validator Icon on my pages that pass validation
and the link works fine when posted on my web site, but it
does not work if I open the web page from a file on my own computer,
saying

No Referer header found!


http://validator.w3.org/check?uri=referer

Has anyone built HTML code that detects no-referer and
instead uses the download page or
Validate by File Upload
http://validator.w3.org/#validate_by_upload
?
