Description
Hello,
Cache-Control field contains in the request header is ignored by FetchFromCacheMiddleware.
So, for example, if the request contains "Cache-Control: max-age=0", the cached page is return instead of build a new version.
According to http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html Cache-Control can be set on the erquest header and may be different from the Cache-Control of the reply.
Regards

I don't believe that Django's cache middleware listens to *any* of the request cache keys, and I'm not 100% sure it should. The goal of the cache framework (I think) isn't to compete with something like Varnish or Squid; I'm fairly sure doing something like this is out of scope.
I'm going to reject this, then, because making this change would be much bigger than just Cache-Control: we'd basically have to turn Django's cache middleware into a proper upstream cache. Feel free to suggest that change on django-dev, but my feeling is that's out of scope for Django.
