Hi,
Tomcat doesn't set any caching headers by itself. To do so, you can
write a simple filter (examples of this filter are freely available on
the net, it's about 10 LOC) that looks at the response content-type and
adds headers as needed.

Ok, I wrote a simple filter. No problem. It works!
One question. Is there a standard way to determine if your filter is being
called during the request chain or during the response chain?

It will add the header once durin

Hi,
No problem about the help ;) Sadly enough, I know most of the Servlet Spec
by heart now. But more importantly, I have filters that do stuff on the
request side, check the response
