Page Caching with clusters and redirect

Rails
1

  1. What’s the behavior of caches_pages when an action returns a
    redirect?
    I’d like to only cache the page if the action renders, but not cache
    the redirect

  2. Any solution for using caching with a cluster of web servers? The
    sweepers won’t fire on the other web servers

It will serve the cached page straight away, no matter what, until the
cache has expired. If you need to do redirects, use action-level
caching with a before_filter.

One solution is to use action caching everywhere and then use a
central memcached server as your fragment store. Whenever you expire
an action, it’ll get expired on that server.
