Yes, XSP all the way through...just kidding. It's MySQL, OJB, java 
code, Flowscript, XSLT, map:aggregate, CInclude and more XSLT, in order 
of appearance on stage.

To control the front-end cache I wrote a simple Action to set these 
HTTP headers as shown in my previous message, then I just add this to a 

                 <map:act type="http-cache-headers">
                     <map:parameter name="cache-validity-seconds" 
                     <map:parameter name="cache-info" value=""/>
                     <map:parameter name="page-info" 

To define how long to cache the page, and add some logging info to 
oversee the whole thing more easily.

Making the front-end cache validity dependent on the content would be 
very easy then.

Great idea, keep the HTML stateless and generate just the tiny 
user-specific bits via javascript - which you can also cache with the 
same mechanism I guess.
