Caching behaviour

Hi,

I'm working on integrating this packing into my project. My main reason for wanting to use the repository pattern is to benefit from a caching layer.

I'm somewhat confused by the caching implementation since it only seems to cache a model per page. I've done some investigation and I can see that the full URL of the page is included in the cache key (CacheableRepository@getCacheKey). What's the reason behind this? I was expecting to be able to cache a model once and then pull it from the cache on subsequent requests regardless of page.

Cheers,
Ben
