Question

I want to prevent my CSSs from being cached on the browser side. How can I do it in embedded Jetty instance?

If I were using xml configuration file, I would add lines like:

<init-param>   <param-name>cacheControl</param-name>   <param-value>max-age=0,public</param-value> </init-param> 

How I can turn that into the code?

Right now I start Jetty this way:

BasicConfigurator.configure();  Server server = new Server(); SocketConnector connector = new SocketConnector(); // Set some timeout options to make debugging easier. // 1 hour connector.setMaxIdleTime( 1000 * 60 * 60 ); connector.setSoLingerTime( -1 ); connector.setPort( 8081 ); server.setConnectors( new Connector[] { connector } );  WebAppContext bb = new WebAppContext(); bb.setServer( server ); bb.setContextPath( '/' ); bb.setWar( 'src/webapp' );  server.addHandler( bb ); 

I think I should search setControlCache somewhere in the WebAppContext area of responsibility.

Any advices on this?

Answer 1

I normally use a ServletHolder, like this:

WebAppContext context = new WebAppContext(); ServletHolder servletHolder = new ServletHolder(MyServlet.class); servletHolder.setInitParameter('cacheControl','max-age=0,public');  context.addServlet(servletHolder, 'myservletpath'); 

While this does not exactly match your code you should be able to figure it out from there ?
