问题
I am using the TemporaryFileUploadHandler to upload files. If a user is uploading a large file and cancels the upload, the file remains in my temporary directory.
Is there a way to trap a cancelled upload (connection reset before a file was fully uploaded) in order to cleanup these files?
The only alternative I can think of is a cron job which looks at the temp directory and deletes files which have not been updates in some reasonable amount of time.

Not sure if it helps, but you may try to connect to django request signals:
request_finished - Sent when Django finishes processing an HTTP request.
got_request_exception - This signal is sent whenever Django encounters an exception while processing an incoming HTTP request.
I think Django should raise error if connection is aborted, so the usage of second one is probably a solution. Please let me know it it helps.
