Giant File Uploads With Rev CGI

Sivakatirswami,

The code for processing "file" uploads is different. We can't use the  
routines we normally use to split stdin. It's a mime enclosure. maybe  
that's what is getting the array wrong.
I have the routines in a library if you want, and they are working  
for me. I'll setup a little demo of file and text upload and then you  
can just change it to suit our needs.

Andre
