Normally the parameter will be added as key="value" unless value is None, in which case only the key will be added. Example: h.add_header('content-disposition', 'attachment', filename='bud.gif') Note that unlike the corresponding 'email.message' method, this does *not* handle '(charset, language, value)' tuples: all values must be strings or None. u _u -u ; N( u Noneu _convert_string_typeu appendu itemsu replaceu _formatparamu _headersu join( u selfu _nameu _valueu _paramsu partsu ku v( ( u4 /opt/alt/python33/lib64/python3.3/wsgiref/headers.pyu add_header� s &u Headers.add_headerN( u __name__u __module__u __qualname__u __doc__u __init__u _convert_string_typeu __len__u __setitem__u __delitem__u __getitem__u __contains__u get_allu Noneu getu keysu valuesu itemsu __repr__u __str__u __bytes__u setdefaultu add_header( u __locals__( ( u4 /opt/alt/python33/lib64/python3.3/wsgiref/headers.pyu Headers s$ u Headers( u __doc__u reu compileu tspecialsu Noneu _formatparamu Headers( ( ( u4 /opt/alt/python33/lib64/python3.3/wsgiref/headers.pyu <module> s
