Uploading multiple/large files

Question

I have this page where a user can upload documents (multiple documents, size limit 10MB each). It is a two step process. Step 1 has the input form. Step 2 is the preview page with a submit button.

How should I handle the scenario where the user closes the browser while on the preview page, without submitting the form? Should I save the files in a temp location after step 1? Is this a decent solution?

And what are the best practices in general for uploading (reasonably) large files?

Thanks.

Take a look at this:

One way or another, you'll probably end up looking at a jQuery/AJAX control to do this.
