Is it possible to take advantage of http caching/proxy caching with dynamic pages? i.e. pages with section/part that can change over time but certain part of the page remain the same. I would rather not keep re-rendering the static part but insure the dynamic part are rendered with fresh data.
I am using memcached mostly as an object store that I can minimize db hits but I still am rendering a bunch of views over and over again. What's the general best practice to deal with something like this.. ##Post controller def show @post = get_from_memcache end ##show.html.erb <div><%= post.body%></div> <div><%= post.created_at%></div> <div><%= post.category%></div> <div><%= Post.favorites_count%></div> The get_from_memcache return a @post object from a cache that basically doesn't expire, because once a post is created, it's body, category, created at etc remains the same. However, in my view I do call another method favorites_count which collects the posts's favorites count from memcache and this favorite keeps changing. This is a simplication of course, there are a few fields that do change. Now If I were to implement some sort of http caching then I would need to do a fresh_when or stale? in my controller method (show), which would essentially not render the views and hence the updated favorites count, unless I use a etag that encompassed the favorite count and other dynamic fields, in which case it kinda defeats the purpose because those fields change regularly. How do I manage this situation? So I can take advantage of a proxy but keep certain dynamic fields in the page updated? One things I can think of is ajax calls to other controller actions to update those fields after page load, but that might ugly.
