Quick start summary

Minimal Web Forms setup

  1. 1. Copy `AjaxUploader.dll` into your site's `bin` folder.
  2. 2. Register the `au` server control in `Web.config` or on the page.
  3. 3. Add the `ajaxupload.axd` handler entry in `system.webServer`.
  4. 4. Create a writable temp folder such as `App_Data\UploaderTemp`.
  5. 5. Add `au:AjaxFileUpload` to a Web Forms page and verify `/ajaxupload.axd` responds.
The local demo notes also call out the main app settings you can tune: temp directory, max file size, chunk size, allowed extensions, and resume support.
