Description
|
|
-----------
|
|
|
|
This directive transforms ``HttpResponse`` and ``ChunkedResponseStart`` messages coming back from its inner route by
|
|
potentially adding the given ``HttpHeader`` instances to the headers list.
|
|
A 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 only a single header you can use the :ref:`-respondWithDefaultHeader-` directive instead.
|
|
|
|
|
|
Example
|
|
-------
|
|
|
|
See the :ref:`-respondWithDefaultHeader-` directive for an example with only one header. |
