| * <p> |
| * |
| * Each HttpURLConnection instance is used to make a single request |
| * but the underlying network connection to the HTTP server may be |

| * Calling the disconnect() method may close the underlying socket |
| * if a persistent connection is otherwise idle at that time. |
| * |
| * <P>The HTTP protocol handler has a few settings that can be accessed through |
| * System Properties. This covers |
