Cache calls to a given URL

[jamesfoster]

The first call to agent.get() should store the response (or the parsed result) and subsequent calls should return the cached result.

Perhaps supply a .refresh() or .reset() method to delete the cache?!

If you are using the client in a browser, you will have the caching behavior of the browser. This works really great. Given that your server sends proper Cache-Control-Headers, you will for example easily fetch a latest version only if the server wants you to fetch it (with If-Not-Modified-Headers and 403 Not Modified responses).

But it could be helpful to add an extra cache, if the server is not under control of the client.
