Resuming an upload

[teseo]

Hello,

I'm pretty much a newbie in Zf2 (I think is awesome!). I am expecting my users to upload big files and I was wondering what's your recommendation within zf2 to allow users to resume an upload in case of browser crash, lost of connection, etc.

I understand of all your samples and they look great but I can't find a way to resume an upload. I did read all the documentation and I couldn't find how to do it. Maybe not supported?

Cheers!

Great question. I haven't done chunked uploads yet personally with PHP, but these links may give some ideas:

It looks like you can potentially read the file in the browser, slice it up into chunks, and do individual uploads of each chunk to the server. Server-side would be responsible for concatenating the uploaded parts.

Also, some cross-browser ways of slicing the file:

Hope this helps!

That is brilliant, is worth to give a try!
