Upload large files with browsers without having it hanging (preferably with flash)

I am trying to upload a lot of files from a browser to a webserver that I have total control of. I've tried to use SWFUpload, but the problem is that my browser hangs when I am uploading a file. The files are supposed to be of any length (up to 2GB due to other restrictions, of course).

While the upload is in progress the browser hangs and the GUI is not updated. When the file is finally uploaded the GUI responds again. In firefox the entire browser stalls 开发者_开发知识库and in Chrome just the tab.

I thought it might have something to do with flash trying to inject the entire file in to the memory first, but that does not seem to be the case (although different test cases yielded different results, but I'm not sure that it's because of that reason).

An applet is also an option, although flash is preferred. The reason I don't want to use a form is because you can select multiple in flash (also possible with Java, I assume) which is a nice feature that I'm going for.

Any ideas? Thought?

If you're using linux, this is a known problem. For Windows users this doesn't happen. Otherwise, you'll have to stick to ajax (the best way is with the jQuery forms plugin). http://www.plupload.com/, this one looks interesting, but I haven't looked into it. You may want to give it a try.

Try an AJAX one: http://sourceforge.net/projects/uber-uploader/

Lighter on the resources and more platform-independent.

client-side I like this jquery plugin:

if you need examples of server-side handling:

I've use this for my projects... http://jupload.sourceforge.net/ I found I had better results though when I used it in FTP mode. I had issues with http uploads. It does support multiple files which is nice. You can upload the files into an "incoming directory" and then process them later when the transfer is finished.
