I would also suspect it to have different behaviours with different
enctypes. The IIS at least acts a bit differently when you try and
upload files with enctype="multipart/form-data".
You need to read the form as binary data, and once you have done that
you can no longer get the QUERY_STRING. It simply dissapears.
It would also be a bit of luck if an undefined situation was implemented
the same way in all browsers and webservers.
