Jetty ProxyServlet with SSL support

Question

I am using Jetty\'s ProxyServlet as a HTTP proxy.

After I start the server and add the socks proxy in firefox I can access websites through the proxy without any pro

Answer 1

ZmK's answer is simply a copy of the example from Jetty repositories and does not even work.

Jetty by default does not have an HTTPS Proxy. The AsyncProxyServlet and ProxyServlet classes only do HTTP proxy. In order for you to do an HTTPS proxy, do the following:

1. Create a class which extends from AsyncProxyServlet class.
2. Override createHttpClient() method. The key here is that the HttpClient instance which you will create will need an SslContextFactory(). Just set SslContextFactory with appropriate settings on HttpClient object and you will be good to go.

Here is the code example in detail: https://github.com/k2k2e6/jettyHttpsProxy

Answer 2

I'm using the latest release of Jetty currently (9.4.1) and I was able to get HTTPS proxy working by simply adding this to my Proxy Servlet:

@Override
protected HttpClient newHttpClient() {        
    return new HttpClient(new SslContextFactory());
}

Credit to k2k2e6's example which I started with before realizing I could just override this simple method instead of the entire createHttpClient() method.

You can use a "ConnectHandler"

http://grepcode.com/file/repo1.maven.org/maven2/org.eclipse.jetty/example-jetty-embedded/8.1.1.v20120215/org/eclipse/jetty/embedded/ProxyServer.java

public class ProxyServer {

    public static void main(String[] args) throws Exception {

        Server server = new Server();
        SelectChannelConnector connector = new SelectChannelConnector();
        connector.setPort(8888);
        server.addConnector(connector);

        HandlerCollection handlers = new HandlerCollection();
        server.setHandler(handlers);

        // Setup proxy servlet
        ServletContextHandler context = new ServletContextHandler(handlers, "/", ServletContextHandler.SESSIONS);
        ServletHolder proxyServlet = new ServletHolder(ProxyServlet.class);
        proxyServlet.setInitParameter("whiteList", "google.com, www.eclipse.org, localhost");
        proxyServlet.setInitParameter("blackList", "google.com/calendar/*, www.eclipse.org/committers/");
        context.addServlet(proxyServlet, "/*");

        // Setup proxy handler to handle CONNECT methods
        ConnectHandler proxy = new ConnectHandler();
        proxy.setWhite(new String[]{"mail.google.com"});
        proxy.addWhite("www.google.com");
        handlers.addHandler(proxy);

        server.start();

    }

}
