问题
I have a web service that accepts really huge files. Usually in the range of 10 - 15 GB (not MB). However upload using a browser is only possible using Chrome on Linux. All 3 major browsers have different flaws trying to upload such a file:
- Internet Explorer stops after exactly 4GB.
- Firefox does not start at all.
- Chrome (on Windows) transfers the whole file but fails to send the closing bondary (send 0xff instead).
Now we are searching for a way to get uploads to work. Preferably using HTML/JS only, but I see no way to make that happen. Second try would be flash, but FileReference seems to break for files > 4GB. Last way would be Java but that is not what we are looking for in the browser client.
Note that this is about the client. I know that the server side code works, as I can upload a 12GB file using standard HTML-Upload with Chrome on Linux. It is the only browser/os combination that works so far, but therefor I am sure, the server coode is fine.
Does anyone know any way to get huge file uploads to work?

There is a fairly young JS/HTML5 API which might cover your user case:

I can't speak to its suitability though.

If you're using IIS, the default max file upload is 4GB. You need to change this in your script or your server settings.

Normally you would break and upload such files in chunks using stream upload. If you take a limited amount data of the file, upload that part to the server, server appends data to the file. Repeat till complete file is uploaded. You can read a file in parts using FileStream (update: Adobe AIR only) or with javascript using the experimental Blob/FileReader. I guess this could be a workaround for the problem.
I think this solution could help: AS3 fileStream appears to read the file into memory
Let me know if this works out, its an interesting problem.
