Add xpath suppot for FormRequest.from_response.
Removing plural from httpcache stats' value names.
Add middleware support for real HTTP caching. Add httpcache setting to allow either real or dummy HTTP caching (for backwards compatibility it's set to use dummy cache by default).
Add middleware support for the 'no-store' Cache-Control directive.
Add cache storage support for real HTTP caching. Add real HTTP caching unit tests for both middleware and cache storage.
Updated the downloader middleware documentation to reflect changes introduced by the support for real HTTP caching.
Implemented policies for HTTP Cache
Remove plural from stat key.
Implement single HTTP cache policy
Merge branch 'master' of git://github.com/scrapy/scrapy into http-cache-middleware
Instead of extending from HttpCachePolicy, following the same approach used for storage selection
default httpcache to rfc2616 policy and improve storage and policy tests
requests with no-cache set must force revalidation of cached responses
Proposed Changes

I was very confused as to how you actually import DjangoItem.
I searched extensively on the internet looking for actual code so I could see how it worked.
I finally found http://blog.just2us.com/2012/07/setting-up-django-with-scrapy/. It is much easier to understand with full files instead of code fragments.
I also edited where it says "we can see that the model is already saved" as I don't see how it's already saved.
Merge pull request #221 from emschorsch/patch-1

Proposed Changes to DjangoItem documentation
Merge branch 'http-cache-middleware', remote-tracking branch 'dangra/http-cache-middleware' into http-cache-middleware
Update downloader middleware documentation
add doc about disabling an extension. refs #132

Split redirection into status and metarefresh middlewares, also changes httpcompression priority. closes #78
