I'm new to the upload extension - I'm able to upload a file async in the App_Data folder but I have the following questions:
1. how to access the filenames which I have uploaded async in the [HttpPost] ActionResult?
(sync is no problem because I have the HttpPostedFileBase Parameter)
2. how to ensure that I have unique filenames?
3. I will save the files in my database after the HttpPost - might be a solution to save the the files in a Session variable or should I save them in the App_Data temporary
