"Referrer" refers to the page that the client came from, so you can't use  
that directly if the client goes through an intermediate page. You'll need  
to call the validator with the full URI, using this:

http://validator.w3.org/check?uri=http://www.example.org

That argument can be passed to your "intermediate" page by the previous  
page (as part of the location string), or it can be extracted as its  
referrer by a script in that pafe (note that this won't work if people  
have their browser set to hide the referrer).

For example, something like this:

document.write ('http://validator.w3.org/check?uri='+document.referrer);

Note that this won't work locally (i.e., when you test the files in your  
system as file:///...), only when you get them through HTTP.

You might want to check if document-referrer is empty before generating  
that line, and give an error message otherwiser.
