YUI Uploader provides file upload functionality that goes beyond the basic browser-based methods. * Specifically, the YUI Uploader allows for: *

    *
  1. Multiple file selection in a single "Open File" dialog.
    2. *
  2. File extension filters to facilitate the user's selection.
    3. *
  3. Progress tracking for file uploads.
    4. *
  4. A range of file metadata: filename, size, date created, date modified, and author.
    5. *
  5. A set of events dispatched on various aspects of the file upload process: file selection, upload progress, upload completion, etc.
    6. *
  6. Inclusion of additional data in the file upload POST request.
    7. *
  7. Faster file upload on broadband connections due to the modified SEND buffer size.
    8. *
  8. Same-page server response upon completion of the file upload.
    9. *
