Hi Vitaly, I don't know about mod_cache, but we're having a similar configuration here (Apache in front, Tomcat serving behind). We experienced that Apache doesn't "touch" any headers when they are served from Tomcat. Unfortunately. there is no option within Tomcat to declare http-headers in the configs, so you have to do that within your code. I've written a filter for Tomcat that sets the header according to our needs, parameters are read as init-params from the filter-specs. Maybe somebody in this list knows a better solution, but that was the only one we found.
