* Example code that uploads a file name 'foo' to a remote script that accepts
* "HTML form based" (as described in RFC1738) uploads using HTTP POST.
*
* The imaginary form we'll fill in looks like:
*
* <form method="post" enctype="multipart/form-data" action="examplepost.cgi">
* Enter file: <input type="file" name="sendfile" size="40">
* Enter file name: <input type="text" name="filename" size="30">
* <input type="submit" value="send" name="submit">
* </form>
*
* This exact source code has not been verified to work.
