The Overflow Blog. The jQuery File Upload Plugin This plugin is extremely full-featured and comprehensively documented, which was exactly the problem I had with it. Some important points: I decided to use a simple JavaScript hashing function to hash the filename for the Session-Id.

It might not need to be numeric, but all the nginx examples I read used numeric filenames, and the Session-Id is used directly by nginx as the filename on disk. As noted in the comment, the response to an individual upload request is a plain-text byte range, which is also present in the Content-Range header.

The plugin uses this value to determine the next chunk of the file to upload. This means that in order to resume an upload, the first chunk of the file must be re-uploaded. Then nginx responds with the last successful byte range, and the plugin will start from there on the next request. This can be momentarily disconcerting, since it looks like the upload has started over.

Set your chunk size accordingly. That is the temp file. Rails provides two extra methods to determine the original filename and the MIME-type:. How are we doing?
