How can I upload large files by chunk, pieces?

Question

I have got a little file sharing webpage. It's free to use it. I would like to upload files between 0mb and 1GB. I'm searching in Google since two days, but I can't find anything what I needed...

My webpage: http://boxy.tigyisolutions.hu However I can upload only 20-30mb now. I would like upload only 1 file at once. But it may be bigger than 500-600mb ... Can anyone help me?

I tried jquery fileupload, but it's uploading nothing for me.

The Blob.slice method will allow you to split up a file client-side into chunks. You must then send each chunk individually. This will only work on browsers that support the File API.

If you don't want to write this code yourself, Fine Uploader is a javascript uploader library that has the ability to chunk files for you and send them to your server.

Hi there, fine uploader didn't work for me, but I found this one: code.google.com/p/swfupload This is great and working for me, there is only one problem yet. I would like use the form demo from demos, but I would like remove the form elements.. but if I remove name, or the other I cant send the form... – Jollity

What do you mean "it didn't work for me"? What specific problem did you have? I can assure you, the file chunking feature works just fine. – Forenoon

error #2038 with this, and I tried swfupload.. same error.. :-( – Jollity

I'm finding it hard to believe that you had this error with Fine Uploader, since I believe this is a Flash-specific error code, and Fine Uploader does not use Flash. – Forenoon

Ok... You are right.. That's name was similar to fineuploader... But now I tried it, but I don't know how to upload file with that.. It doesnt upload anything for me... However swfupload works now. That's very easy to use... The problem is only: i get 2038 error with that if i try upload 600+MB... I can upload 100-300MB with no problem... :-) I have edited php.ini for max upload size 2500MB, and timeout for 9999.. and FcgidMaxRequestLen to 2147483648 bytes ... but with large files 2038 error... – Jollity

@RayNicholus why should the large files be divided to chunks for uploading them ? – Ungrudging

so does this mean we have to make multiple http request to the backend server for each chunk? – Barfuss
