Problem using referrer to validate XHTML pages...

Hi,
 
I'm testing a new design for our site, and it's validating as XHTML 1.0 just
fine. I'd like to include a link to the validation in the site footer for
each redesigned page on the site.
 
When I use the code snippet on the validation page, it doesn't work. Here's
the snippet I'm using:
 
<a href="http://validator.w3.org/check/referer">Valid XHTML</a>
 
This works fine for the CSS validator: <a
href="http://jigsaw.w3.org/css-validator/check/referer">valid CSS</a>, but
not for the XHTML.
 
Since this will be in the footer, I can't include the URI of each page:
<http://validator.w3.org/check?uri=http%3A%2F%2Fwww.sanjuan.edu%2Fbenefits%2
Ftest.shtml>
http://validator.w3.org/check?uri=http%3A%2F%2Fwww.sanjuan.edu%2Fbenefits%2F
test.shtml 
 
Any ideas?
 
Thanks...
