I found what was interfering with the caching: it's sitemesh. I have
this filter-mapping:
<filter-mapping>
<filter-name>sitemesh</filter-name>
<url-pattern>*.jsp</url-pattern>
</filter-mapping>
If I remove that, it works fine. Once I found that, I realized that
adding the page pattern to the sitemesh exclude list solves the
problem. I don't understand what/how sitemesh is doing to the page to
make it uncacheable, but that's a different issue.

I am having trouble getting the "Included Pages" example from
http://www.caucho.com/resin-3.0/performance/caching.xtp to work. I am
running Resin 3.0.22 Professional on Mac OS 10.4.8. I turned on cache
logging, then created these files as described on that page:
expires.jsp:
<%@ page session="false" %>
<%
long now = System.currentTimeMillis();
response.setHeader("Cache-Control", "public");
response.setDateHeader("Expires", now+(5*60*1000));
%>
now=<%= now %>
test.jsp:
<%@ page session="true" %>
this is test.jsp
<jsp:include page="expires.jsp" />
I loaded expires.jsp via wget. The headers have Cache-Control: public
and Expires: Tue, 30 Jan 2007 17:23:59 GMT, and the cache log says
caching: /test/expires.jsp expires=Tue, 30 Jan 2007 17:23:59 GMT
length=20. I used wget to load test.jsp, but it doesn't use the
cached expires.jsp. It doesn't cache it again either -- there's
nothing in the cache log at all. I loaded expires.jsp immediately
after, and it again used the cache.
One thing I noticed is that when I load expires.jsp, the log says it's
creating a session even though I have session="false". I tried
checking the value of session in expires.jsp, and as I'd expect, got a
compile error for undefined symbol.
I also tried restarting resin and repeating the same sequence using
Firefox, setting response.addHeader("Cache-Control", "max-age=300")
instead of the Expires header, changing the include path to be
absolute (/test/expires.jsp), and setting Last-Modified instead of
Expires and adding the path to the cache-mapping section in
resin.conf. What am I missing?
Thanks for your help,
Kimberly Nicholls
