The problem is, form['data'] is not initialized (adding .value doesn't
helptherefore).  
Probably the header which is send by the httplib-programm:
 hdr.append('Content-Disposition: form-data; name="data"') 
is not well stated - I don't know how the naming of a field could be done 
in a python script using httplib. In a web-form it works by using 
this field and a submit (button) statement.

Thanks for help!


Cheers,
Dirk
