Subject RE: How do you set cache-control for static (gif, jpg) resources
Date Fri, 30 Jul 2004 12:58:23 GMT

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.
