After using the HTML4.0 (and CSS) validators it for my pages from...
(a kind of terminology dictionary, that uses parameters to point to various

...I noticed the results page always came back not recalculated, unless I
specifically asked for a refresh. Going further, I found the answer from the
validator does not include any cache-control directive or other form of
cachebuster, to prevent browsers from reusing the previous results page.

Maybe it would be a good idea to add something along that line ? For
instance, the simple fact of changing the default link code from:

  <a href="http://validator.w3.org/check/referer">
    <img border=0 src="http://validator.w3.org/images/vh40"
      alt="Valid HTML 4.0!" height=31 width=88></a>

to something including the page URL would already remove most client-side
caching. Like:

    <img border=0 src="http://validator.w3.org/images/vh40"
      alt="Valid HTML 4.0!" height=31 width=88></a>

Or maybe not ? I noticed nothing about this in the mailing list archive.

Best regards.
