I've got an application for users(which currently works) to upload very large files (~150M😎. The problem is that it takes until the file is completely uploaded to give feedback to the user and/or allow then to submit another pair of files. I'm using some javascript to at least give them some feedback (and prevent double submits).
I've been trying attempting to launch new windows and having simultaneous uploads (having different POSTS), but I only seem to be able to upload 1 file per session --- is there a way to initiate new sessions in the child windows so I can handle more than one upload at time per user?
