Fighting client-side caching in Django

Question

I'm using the render_to_response shortcut and don't want to craft a specific Response object to add additional headers to prevent client-side caching.

I'd like to have a response that contains:

• Pragma: no-cache
• Cache-control : no-cache
• Cache-control: must-revalidate

And all the other nifty ways that browsers will hopefully interpret as directives to avoid caching.

Is there a no-cache middleware or something similar that can do the trick with minimal code intrusion?

Answer 1

You can achieve this using the cache_control decorator. Documentation is here. Example in the documentation:

from django.views.decorators.cache import never_cache

@never_cache
def myview(request):
   # ...

Answer 2

Actually writing my own middleware was easy enough:

from django.http import HttpResponse


class NoCacheMiddleware(object):

    def process_response(self, request, response):

        response['Pragma'] = 'no-cache'
        response['Cache-Control'] = 'no-cache must-revalidate proxy-revalidate'

        return response

Still doesn't really behave like i wanted but so neither does the @never_cache decorator
