Well, if you are using the python-boto library, this patch will not work for you. I have not tested boto with django-storages, sorry. Try the other backend library for django-storages. With boto you need to configure the /etc/boto.cfg file.

I’m confused, what is actually referencing the S3.py file that would make these changes make a difference? These changes are to be made on S3.py, right?

Check that S3 is not using versioning if you are replacing files. Also, there is a bug as it is linked on the post, please check the issue #56 of the django-storages and follow my patch, rather than using those example lines on the issue comments.

If you do not want to use the localized date, you should use a GMT version that works, as follows:

    def _add_aws_auth_header(self, headers, method, bucket, key, query_args):
        if not headers.has_key('Date'):
            headers['Date'] = time.strftime("%a, %d %b %Y %H:%M:%S +0000", time.gmtime())

        c_string = canonical_string(method, bucket, key, query_args, headers)
        headers['Authorization'] = 
            "AWS %s:%s" % (self.aws_access_key_id, encode(self.aws_secret_access_key, c_string))

I wish I could get this working properly. When django requests the image I have stored on S3 it will never get a 304, but when I copy the link to the image and paste it in a new window it will first 200, then any requests after will 304… Frustrated. Any tips?

I have set the AWS_HEADER variable in my settings like specified in the django-storage docs. Are you suggesting that everything you mentioned above must be done in order to get a 304?
