Architecture
The architecture for an AJAX file upload request in a application consists of two core components:
Web 2.0 runtime
Supports the FileUpload widget to enable users to submit AJAX file upload requests.
AJAX channel
Enables AJAX file upload requests to be submitted to and processed by the application server.
Both the Web 2.0 runtime and the AJAX channel can be extended and customized by an alpha developer.
