enctype either the file is uploaded or only the pathname
of the file is transferred.
This page contains a form including a file input box. The form is submitted
using a GET request, i.e. the CGI parameters
will appear in the URL bar. The enctype is set to
application/x-www-form-urlencoded, i.e. the filename should
be sent, not the file.
To exhibit this Mozilla bug, browse your file system, choose a file, submit the form and check
the value of the parameter path. It will only contain the filename that
you've choosen but not the path to it.
