HttpResponse acts like a dictionary with respect to headers. It's a common
middleware pattern to set headers ''unless'' they've been explicitly set
by the view. eg.
{{{
class MyMiddleware(object):
def process_response(self, request, response):
if not 'X-Test' in response:
response['X-Test'] = 12345
return response
}}}
Having a `setdefault()` implementation would simplify this (not much in
the trivial one-header case, but for example CORS middleware where you're
setting a number of headers)
{{{
class MyMiddleware(object):
def process_response(self, request, response):
response.setdefault('X-Test', 12345)
return response
}}}
