      Description



      Name: dfC67450 Date: 12/07/99



      If we call getContent() method of URL, read the byte from returned InputStream,
      close this stream and then call getContent() again we will get new InputStream
      but different with the first one.

      Note: To get the same stream after closing we can
      insert Thread.sleep(10000) before second invoÓation of getContent().


      Here is the test demonstrating the bug:

      ---------------------------------------------

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

      public class URLTest {
          public static void main (String args[]){

              try {
          
                  if (args.length == 0) {
                      System.out.println("url parameter required");
                      return;
                  }
          
                  URL url = new URL(args[0]);
                  System.out.println("url: " + url);
                  Object obj = url.getContent();
                  int c1 = ((InputStream) obj).read();
                  ((InputStream)obj).close();
                  // Thread.sleep(10000);
                  obj = url.getContent();
                  int c2 = ((InputStream) obj).read();
          
                  if ( c1 != c2) {
                      System.out.println(c1 + " != " + c2);
                      System.out.println("Test failed");
                      return;
                  }
          
              } catch (Exception e) {
                  System.out.println("Unexpected exception:" + e);
                  return;
              }
          
              System.out.println("Test passed");
              return;

          }
      }
