Hi,

There is nothing in the header or the body for that matter that is part 
of the HTML 4.0 spec. If you are in control of the URL/page used then 
you can add a tag set to your HTML that will state that your stuff is 
really there. In other words if your custom tag set is missing from 
your pages then it must be 404 for your URLs. You can use: <not 
404></not 404> in all your destination URLs and they will just be 
ignored by browsers during rendering.

I guess you're out of luck if you are building a browser.
