Since there are so many php and java programs of this kind, but none for BaCon.
Here is an as short, but as clear as possible little program to upload a file from your browser to your webserver.
Put this in your cgi folder of your webserver.
Tested with Apache, but should work with Hiawatha.
In a BaCon webserver, unfortunately, I cannot get this to work, that is still too difficult ;-(
Tested with text files, images and BaCon executables, but should work with all kind of files.
Please let me know.
