add GzipFilter first, before GuiceFitler and CORSFilter

Answer 2

But when using a ServletModule installed on your injector you can just add it in your module configureServlets() function like this.

    final Map<String, String> params = Maps.newHashMap();
    params.put("mimeTypes", "text/html,text/xml,text/plain,application/javascript,application/json");
    params.put("methods", "GET,PUT,POST,DELETE");
    params.put("deflateCompressionLevel", "9");
    bind(GzipFilter.class).in(Singleton.class);
    filter("/*").through(GzipFilter.class, params);
