Preparing your application for serving static content efficiently

(Reposted from the Empower Campaigns blog)

Most web applications have static content such as CSS, JS, images, etc.  To save on bandwidth costs and improve load times for your users, it's a good idea to tell the client to cache these items for a long period of time.  But even though your static content changes infrequently, when it does, the cached content needs to be invalidated.  In addition, high traffic sites often want to go a step further and take advantage of a CDN to offload static content delivery.  Below I'll share the method we used here at Empower Campaigns to accomplish both of these things.
