Caching with Etags Discussion
Can I use this with associations in views?
I have post with author and use fresh_when on post. If I change author will it render on post view old author or new one?
Does it make sense using this for an index page if it has pagination?
So basically this tells browsers that have already downloaded a copy of this version of this URL - hey, the URL has not changed?
Or this caches the whole page on Rails side and re-sends the Rails' HTML to the browser?
