remove uploaded file when server got 400 or 499 error during resumable upload

[WraithKim]

Hi, I am using nginx-upload-module in my web server. And thank you for this awesome module!
But I had some trouble with resumable upload.

I implement chunk file upload using jQuery-File-Upload. But when I disconnect upload session for resumable upload test, nginx returns 400 or 499 error.

This is normal error handling but I set the upload_cleanup 400 404 499 500-505; on my server config, so my nginx removes partially uploaded file. Therefore, even if i resume uploading, I got incompleted file.

Temporary, I change my config to upload_cleanup 404 500-505; . But is it right way?
