Well...as I said before, the cache settings on the HTML will not affect the caching on
the images referenced in the HTML.
I use:
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache");
response.setHeader("Cache-Control", "no-store"); // If I remember correctly,
this stops proxy server caching
response.setHeader("Cache-Control", "private");
which is probably a bit of overkill, but it seems to work. This should work with
images as well as HTML, but I haven't tried to serve up images from servlets, so I'm
not absolutely positive.
So, to answer your question: No, there isn't a "no-cache" HTML tag for images, as
images are not HTML. You can, however, set the HTTP headers (as shown above) to give
you the same result.

I'm setting the "no-cache" in the html meta-tag and I was actually
suspecting that it was not functionning because the image was generating
another request. My problem is how did I tell the browser to not cache
this image? Is there a "no-cache" tag for images?
Thanks,
Stephane
