hi,
i get this error when i send a page that has a form on it that uses POST method,
if i change the method to GET it works fine tho.

and the POST test on the hunchentoot's own test site gives me this too.

here is the stack trace:

#<SB-IMPL::STRING-INPUT-STREAM {F0BC191}> is not a binary input stream.
   [Condition of type SIMPLE-TYPE-ERROR]
