Question

XMLHTTPRequest fails when I send a large file (>700MB) over .send(). Even worse, BlobBuilder fails for large files with append() as well. Is there a way to send a file in multiple chunks using XMLHTTPRequest? How do I tell the server to “append” the following stream of data?

Answer 1

If you have control of the server as well as the client, I’d suggest the following workaround:

1. break the file up into chunks (.slice())
2. upload the multiple file chunks
3. reassemble the file chunks on the server

I don’t know that this problem can be solved strictly within the browser.
