Flash
Flash is very "buggy" thing :]

should be only 200 OK
.
Settings
Flash settings. It is advisable to place flash on the same server where the files will be uploaded.

Chunked file upload
Client and server communicate to each other using the following HTTP headers and status codes.
Client explicitly sets the following headers:
- Content-Range: bytes <start-offset>-<end-offset>/<total>
- Content-Disposition: attachment; filename=<file-name>
Response codes:
- 200 - last chunk is uploaded
- 201 - chunk is successfully saved
- 416 - range is not acceptable error, recoverable
- 500 - server error, recoverable
