Django cache Bad Request (400)

Question

I currently have my seetings file configures to use the memcache cache.

'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache'

Whilst the site runs flawlessly, I see debug lines such as:

[05/Dec/2014 15:28:53] code 400, message Bad HTTP/0.9 request type ('get')
[05/Dec/2014 15:28:53] "get :1:views.decorators.cache.cache_header..439e23553bea98b3b35e7b94c1f72576.en-gb.AUS_Eastern_Standard_Time" 400 -
[05/Dec/2014 15:28:53] "GET /RSA/ HTTP/1.1" 200 968

So I'm interested in learning how to fix this, and how I can actually test whether the backend cache is being used. It is currently implemented to be used with all pages.

Went back to the docks and started playing around with the port number for the location.

Was able to make it report a different error that referenced 63894 as being the correct port number. Interesting to note that it was not the port the actual site was running off - 88. Maybe it was something to do with the fact that it was running with the django manage.py runserver command and was only a development server etc.

Anyway this fixed the problem. Code below as a reference.

CACHES = {
        'default': {
            'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
            'LOCATION': '127.0.0.1:63894',
        }
    }

Adapted from previous response

The only possible reason I see in bad request error is due to misconfiguration of hosts settings as also discussed here.

Also to check for memcached, Please check this link.

So I already have ALLOWED_HOSTS set up. However, attempting to import the cache form within the shell gave: `>>> from django.core.cache import cache cache.set('key', 'value') File "", line 1 from django.core.cache import cache cache.set('key', 'value') ^ SyntaxError: invalid syntax` – Red Shift Dec 07 '14 at 23:49
