import java.util.concurrent.ConcurrentHashMap;

import static nginx.clojure.java.Constants.PHASE_DONE;

import nginx.clojure.ChannelCloseAdapter;

import nginx.clojure.java.NginxJavaFilterRequest;

import nginx.clojure.java.NginxJavaHeaderFilter;

public class ResponseFilterHeaders implements NginxJavaHeaderFilter {

static Map<Long, NginxJavaFilterRequest> headerFilterRequests = new ConcurrentHashMap<Long, NginxJavaFilterRequest>();

public ResponseFilterHeaders() {

}

@Override

public Object[] doFilter(int status, Map<String, Object> request, Map<String, Object> responseHeaders)

throws IOException {

System.err.println("============= Inside invoke ResponseFilterHeaders =============");

System.err.println(status);

System.err.println(request);

return PHASE_DONE;

}
