Description
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
This directive transforms ``HttpResponse`` and ``ChunkedResponseStart`` messages coming back from its inner route by
|
|
|
|
|
potentially adding the given ``HttpHeader`` instance to the headers list.
|
|
|
|
|
The header is only added if there is no header instance with the same name (case insensitively) already present in the
|
|
|
|
|
response. If you'd like to add more than one header you can use the :ref:`-respondWithDefaultHeaders-` directive instead.
