Hello! I'm trying to achieve cache site. Launched memcached,
made the necessary adjustments:
CACHE_BACKEND = 'memcached://unix:/home/username/memcached.sock'
CACHE_MIDDLEWARE_SECONDS = 600
CACHE_MIDDLEWARE_ANONYMOUS_ONLY = True
added two middleware entries as it stated in the documentation
MIDDLEWARE_CLASSES = (
'django.middleware.cache.UpdateCacheMiddleware',
...
'django.middleware.cache.FetchFromCacheMiddleware',
)
when requesting different pages on my site, I noticed that memory that
memcached process occupied
is growing - it is correct. Hence, apparently the page is cached.
But now when I request the page, I always get an answer similar to
this:
200 OK
Date Mon, 14 Mar 2011 18:04:43 GMT <--- always put the current server
time
Expires Mon, 14 Mar 2011 18:14:43 GMT <--- current time + 10 minutes
Last-Modified Mon, 14 Mar 2011 18:04:43 GMT <--- current time
Cache-Control max-age = 600
It looks as if the page is taken not from the cache and generated each
time I request it.
I checked memcache work: connected to it, tried to SET GET DELETE
STATS - everything works fine.
As stated in djangobook:
> Additionally, the cache middleware automatically sets a few headers in each
> HttpResponse:
> * Sets the Last-Modified header to the current date/time when a fresh
> (uncached) version of the page is
> requested.
So why I have Last-Modified set to current time everytime I try to
load page?
What could be the problem with fetching cached pages?
How are such problems identified?
Has anyone encountered a similar problem?
Thanks in advance!
