[hunchentoot-devel] Why can't the python script get the post parameters from hunchentoot-cgi?

The hunchentoot-cgi basically works with hunchentoot-1.2.2 now with a few  
modification:
1. In #'handle-cgi-script, replacing :external-format tbnl::+latin-1+ with  
:external-format tbnl::+utf-8+
2. As WhiteCat suggested, use #'make-pathname as below:

(pushnew (hunchentoot-cgi::create-cgi-dispatcher-and-handler
           "/cgi-bin/"
           (make-pathname :directory '(:absolute "media" "E" "myapp"  
"cgi-bin")))
          dispatch-table :test #'equal)

However, I do not understand why the python script cannot get the POSTed  
parameter,
i.e., when visiting http://127.0.0:8000/cgi-bin/login.py?cmd=view,  
login.py can get the parameter cmd's value sucessfully,
  but when posted by the following form, login.py cannot get all the posted  
values (no matter hidden or not):

<html><body>
   <form method='POST' action='cgi-bin/login.py'>
     <input type='text' name='userid'>
     <input type='password' name='userpwd'>
     <input type='submit' value='Login'>
     <input type='hidden' name='cmd' value='view'>
   </form>
</body></html>

I guess hunchentoot-cgi does not pass the posted parameter(s) to the  
python script according to the environment:

Please shed a light on me, thanks!
