A jquery, flash solution for upload files with progress bar.
With the use of flash, when browse for files, multiple file can be selected which could not be provided in the IE7,8 browsers.
However, you should take note for the ASP.NET.
Notes for the ASP.NET:
Window Authentication cannot be used due to the limitation of the flash which does not properly handle HTTP Authentication (or you need to write a page which allow anonymous access)
Forms Authentication can still be used but you need to search about the custom handling.
HTTP Authentication is handled at the Web Server/Browser level with HTTP response codes and HTTP headers.
Once authenticated the browser remembers that you already authenticated to this site and just sends the auth data with each request (otherwise you’d have to re-auth with every request).
Requirement: Flash and jQuery.
