The most efficient way to go about this in my opinion is to use the mchttpd
stack as guide for how things can work, do the research on the appropriate
protocol and start working on it. From your description above I gather you
have a pretty good understanding of how to approach it.
I suggest using an address of type
"http://www.user:[EMAIL PROTECTED]/dir/script.cgi" for authentication. The
cgi checks the user/password and reads from socket the file to be uploaded.
If authentication fail the cgi returns an error.
