24   * {@link org.apache.commons.fileupload.FileItem} instances which keep their
25   * content either in memory, for smaller items, or in a temporary file on disk,
26   * for larger items. The size threshold, above which content will be stored on
27   * disk, is configurable, as is the directory in which temporary files will be
28   * created.</p>
29   *
30   * <p>If not otherwise configured, the default configuration values are as
31   * follows:
32   * <ul>
33   *   <li>Size threshold is 10KB.</li>
34   *   <li>Repository is the system default temp directory, as returned by
35   *       <code>System.getProperty("java.io.tmpdir")</code>.</li>
