all subsequent requests return the same exception.  to reproduce these results, 
run the following test program with something like "java Main 10000 
http://localhost:8080/cocoon/";



import java.net.*;
import java.util.*;
import java.io.*;


public class Main
{
  public static void main( String[] args ) throws Exception
  {
    if( args.length < 2 ) {
      System.err.println("usage: Main (iterations) (url)+");
      System.exit(1);
    }

    int iterations = Integer.parseInt(args[0]);
    for( int i=1; i<args.length; i++ ) {
      String urlStr = args[i];
      time(iterations, urlStr);
    }
  }


  private static void time( int iterations, String urlStr ) throws Exception
  {
    URL url = new URL(urlStr);
    int[] times = new int[iterations];

    for( int i=0; i<iterations; i++ ) {
      long start = System.currentTimeMillis();
      getURL(url);
      long stop = System.currentTimeMillis();
      times[i] = (int) (stop-start);
    }

    int maxTime = 0;
    int minTime = Integer.MAX_VALUE;
    long avgTime = 0;

    for( int i = 0; i < times.length; i++ ) {
      int time = times[i];
      minTime = Math.min(time,minTime);
      maxTime = Math.max(time,maxTime);
      avgTime += time;
    }
    avgTime /= times.length;

    int perSec = (int) (1000L/avgTime);

    System.out.println();
    System.out.println(url.toString());
    System.out.println("max time: "+maxTime);
    System.out.println("min time: "+minTime);
