File Watcher Task

The File Watcher Task does what it says really, it watches a folder waiting for files. When an available file is found the task completes, returning the name of the file for later use.

The task will detect changes to existing files as well as new files, both actions will cause the file to be found when available. A file is available when the task can open it exclusively. This is important for files that take a long time to be written, such as large files, or those that are just written slowly or delivered via a slow network link.

Asynchronous client script callbacks

There has been a lot of interest in the web-facing community lately about a new useability feature that goes by a number of different names—XMLHTTP, AJAX, out-of-band requests, and asynchronous client script callbacks, to name a few.

Regardless of the name, this feature provides a way for a standard web page to make calls back to the server, without a traditional page refresh. The user is oblivious to the fact that a server call has occurred, and is not interrupted by it.
