django-postleware

#################

A simple django middleware class which injects a `Cache-Control: no-cache`

header onto POST responses.

Installing

##########

1. `pip install django-postleware`

2. Add the middleware to `settings.py`

.. code-block:: python

 

    MIDDLEWARE_CLASSES = (

        'postleware.PostResponseCachebusterMiddleware',

        # ...

    )

Why?

####

Mobile Webkit (iOS4+ and Android stock bowser) has a bug that causes it to

cache similar POST requests when it clearly shouldn't. Rather than only caching

requests that have a specific `Cache-Control` header, it does the opposite and

caches the request unless the `no-cache` value is present in the POST response.

Not working for you?

####################

Let me know by opening an issue or pull request. This was enough for me, but I

have read around the webs that other devs needed to add additional headers to

the response before it would stop caching.
