Well, that's a limit, isn't it?

What happens when we try to upload a very large file is after about 
300 mb we get the following error:

         500 null

And it's not a time-out thing. I tested this by logging in via Remote 
Desktop and uploading an 800 mb file which took under a minute (as 
you'd expect).

So maybe it's an IIS thing? I have the CF JVM Heap Size set to 1024, 
if that matters. What other configs can I change?

Is there a way to have the file(s) spool straight to the hard drive 
instead of to memory (which seems a little silly if you ask me). 
Better yet, to a particular HD and folder?

I know, I know. Several people have said I'm crazy for trying to 
accept very large files via HTTP, but we want to integrate the upload 
into the application. FTP moves us out of the application and adds a 
bunch of security and synchronization issues. Plus, the people who 
want to do these very large uploads will be doing so over an internal 
network (University) so the uploads won't take very long.
