      Description



      Name: rlT66838 Date: 11/10/99


      java version "1.2.2"
      Classic VM (build JDK-1.2.2-001, native threads, symcjit)

      The sample code demonstrates a problem using HTTPS to communicate with a web
      server under IE. Under Netscape this code works exactly as intended (to print
      out the contents of the stream from the web server for the given URL).

      Note: The HTML was converted using HTMLConverter version 1.2, the exact plugin
      specified is not 1.2.2, however, as shown by the Plug-In Java console window the
      correct plugin is being executed. Manually editing the HTML to point
      specifically to the 1.2.2 plugin does not change the results of this test.
