Error with linking in.

I have found that the advertised method of linking into the Validator doesn't work anymore.

When I validated before, I was given the xHTML ok image and href link, which when I put on my site (and find on other sites such as www.w3cschools.com) could click on it and have the page validated directly.

This no longer seems to work, and instead brings up a URI Scheme error:


=====================================================
Sorry, this type of URI scheme (undefined) is not supported by this service. Please check that you entered the URI correctly. 

URIs should be in the form: http://validator.w3.org/


=====================================================


Even your own xHTML ok image link from the validator at the bottom of the page brings up this error.

Have you altered the method or URI for coming into the validator from an outside web page??
