I can't recall if I've made any changes to this, but I
recall testing it and I think it worked for me.

REBOL [
Title: "multipart POST"
Date: 15-Sep-1999
Version: 1.2
File: %POST.r
Author: "Andrew Grossman (modified by: Luis Rodriguez J
-.29-April-2000)"
Email: [grossdog--dartmouth--edu]
Owner: "REBOL Technologies"
Purpose: {
To decode multipart encoded POST requests,
including file uploads.
}
Usage: {
Call this file in your CGI scriptand do
decode-multi with a
file argument of the directory where uploaded
files will go and
a logic argument to set whether files will be
given the field they
were
uploaded as as a name. Files are saved and
variables are decoded
and
set.
}
Notes: {
Fixed problem recognizing EOF.
Functionality is now rock solid. Function
calls won't change, so this is certainly useable.
See the comment in the decode-multi function if
you need mime types.
Tested with MSIE and Netscape for Mac.
