Byron, >> Very curious to know what the scenario is for this requirement.
The original requirement was that I was working with a file upload system (Plupload) utilizing the chunk method for uploading files. We needed a way for users to use HTTP to upload gig sized files. In the basic implementation of the system each chunk of the file is uploaded to the server with three multipart form fields; Name, chunk, chunks which contains the actual file name, the chunk being sent and the total number of chunks to send. Each chunk is sent as blob. In testing I found that if someone opened the upload page in two or more browsers windows (as a way of bypassing the number of files at a time in the queue) and started two upload sessions they could easily upload a different file with the same name simultaneously. There was no way to determine which window uploaded which chunk of two different files with eh same name so on the server receiving end they would become intermixed and the file would be corrupted. My first thought was that I needed a way to either to uniquely identify that there were two separate windows of the upload page opened and send that identifier within the extended multipart form fields. In investigating I found that instead I could uniquely identify each file from each instance of the window (see my other thread) even in the same session and thereby prevent file upload corruption.
