Caches object

The Caches object represents a collection of named caches and members to interact with those caches. The interface provides methods to open, create, iterate, and remove individual caches. You can also match cached responses over all the named caches without interrogating each one.

caches.open

The caches.open method returns a reference to a cache matching the name that's supplied. This reference is a Cache object, which is detailed in later sections. If a cache matching the name does not exist, a new cache is provisioned. This returns a promise; resolving a cache object allows you to manage cached responses in that cache:

caches.open(cacheName).then(function (cache) { 
//do something here 
}); 

caches.match

The caches.match method is a convivence method that works similarly to the cache.match method. It returns a promise that resolves to the first cached response matching the Request object passed to the method.

The nice thing about the caches.match method is how it handles interrogating...
