I'm planning to get back to your pull request and commit some form of it
before Django 1.3 -- just haven't gotten there yet.
> If we want users to be able to save memory by not caching user-specific
pages, I have a patch to do that with a separate setting, but
`CACHE_MIDDLEWARE_ANONYMOUS_ONLY` must die soon. My patch provides a
reasonable transition behavior for existing users of the setting before it
goes away completely.
What do you see as inadequate about your pull request mentioned above, as
a way to preserve CACHE_MIDDLEWARE_ANONYMOUS_ONLY? Why do you think it
needs to go away completely, and/or be replaced by another setting?
I understand that simply caching all requests is often fine, since the
caching will vary by cookie anyway and won't result in the wrong content
being shown to a user. But in some cases it's still useful to be able to
easily turn off caching for all user-variable pages, since for some sites
they may be the pages with the most dynamic content (and caching with
Vary: Cookie eats up cache memory a lot faster).
