Re: [jetty-users] Disable Cache of Static Content in Embedded Jetty

Hi Greg,

Thank you for your reply.

My embed code actually defines a web.xml descriptor with the following relevant snippet:

    <!-- Default Jetty Servlet for static content and directory listings !-->
      <servlet>
          <servlet-name>default</servlet-name>
          <servlet-class>org.eclipse.jetty.servlet.DefaultServlet</servlet-class>
          <init-param>
            <param-name>dirAllowed</param-name>
            <param-value>true</param-value>
        </init-param>
      </servlet>

      <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

Following your lead of checking the descriptor I found this:
http://download.eclipse.org/jetty/stable-9/apidocs/org/eclipse/jetty/servlet/DefaultServlet.html

Which references settings like:

    maxCacheSize : 0 for no cache
    cacheControl : If set, all static content will have this value set as the cache-control header.

I will try to either of those and hopefully that's all I need.

Thanks,

Igal,

I don't think it is the jetty cache, as that only applies to static content rather than JSPs.
It is probably the configuration of the JSP Servlet, which would be in the webdefault.xml descriptor included in the jetty-servlet.jar

The other thing to check is that it is not the browser cache.

regards

Hi,

How can I disable the caching of static content in embedded Jetty?

My embed code is like so (removed unrelated lines):

WebAppContext webapp = new WebAppContext();
webapp.setConfigurationClasses(new String[]{

    "org.eclipse.jetty.webapp.WebInfConfiguration"
   ,"org.eclipse.jetty.webapp.WebXmlConfiguration"
   ,"org.eclipse.jetty.webapp.MetaInfConfiguration"
   ,"org.eclipse.jetty.webapp.FragmentConfiguration"
   ,"org.eclipse.jetty.webapp.JettyWebXmlConfiguration"
   ,"org.eclipse.jetty.annotations.AnnotationConfiguration"
});
Server server = new Server();
server.setHandler(webapp);
WebSocketServerContainerInitializer.configureContext(webapp);
server.start();

The problem is that I have a _javascript_ file that is not updating when I modify it.  The browser (Chrome) keeps showing "200 (from cache)" and the contents are unchanged.

Any ideas? TIA!
