Tomcat: Cache-Control

Question

Jetty has a CacheControl parameter (can be specified webdefault.xml) that determines the caching behavior of clients (by affecting headers sent to clients).

I don't believe there is a configuration to do this. But it should not be much of an effort to write a filter to set the Cache-Control header on a per webapp-basis. E.g.:

public class test implements Filter {

        public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
                throws IOException, ServletException {

            chain.doFilter(request, response);
            ((StatusResponse)response).setHeader("Cache-Control",
                    "max-age=0, private, must-revalidate");
        }

        public void destroy() {}

        public void init(FilterConfig arg0) throws ServletException {}
}

And you'd place this snippet into your webapp's web.xml file.

    SetCacheControl
    ch.dietpizza.cacheControlFilter
                       

    SetCacheControl
    /*
