I think you need to explain your problem more fully. Are you using Amazon's webservers as in the link you posted to? Exactly what problem are you trying to solve by caching, and what are you trying to cache and where to you want to cache it?

Hye Colin ! Firstly thank you for your answer ! I try to caching my pictures on my app serv on the public folder of my rails app, i'll create a sub folder cache.{id-user} I launch a function which return me a array of url, like that "http://www.bytebob.com/images/ruby.png" and in my view I do a loop by .each, and for every occured, it puts <img src="{url}"> So it make some time to get url, and I want caching the .png/.jpg/... file, like a thumbnail, on a folder to increase speed Like that it'll take some time just one time, when user connect !
![http://www.bytebob.com/images/ruby.png"](http://www.bytebob.com/images/ruby.png"){kind=link}
I don't understand why cacheing the images will make it quicker. Where are they coming from in the first place?
Also could you please not top post, it makes it difficult to follow the thread. Insert you reply at appropriate places in previous messages, thanks.
