/**
 * Default factory giving {@link Attribute} and {@link FileUpload} according to constructor.
 *
 * <p>According to the constructor, {@link Attribute} and {@link FileUpload} can be:</p>
 * <ul>
 * <li>MemoryAttribute, DiskAttribute or MixedAttribute</li>
 * <li>MemoryFileUpload, DiskFileUpload or MixedFileUpload</li>
 * </ul>
 * A good example of releasing HttpData once all work is done is as follow:<br>
 * <pre>{@code
 *   for (InterfaceHttpData httpData: decoder.getBodyHttpDatas()) {
 *     httpData.release();
 *     factory.removeHttpDataFromClean(request, httpData);
 *   }
 *   factory.cleanAllHttpData();
 *   decoder.destroy();
 *  }</pre>
