Upload

This class implements an easy interface to upload files to a webserver.  It’s built using standard only functionallity in ASP.  It will automaticly start parsing the binary stream sent by the browser which might take a while if the uploaded files are large.

Notes

Large parts of this code is based on code by Gez Lemon of Juicy Studio http://www.juicystudio.com/.  It has been and partially rewritten and enhanced by CrazyBeaver Software along with it’s new class interface.
