Cache Cookie Session

The operations of these three objects are quite similar, with some minor differences in the API and storage locations.

Cache: Stored in memory, with an optional expiration time (default is 2 hours).

Cookie: Stored in the browser's request header, with an optional expiration time (default is 1 day).

Session: Stores a session key in the cookie, while the session data is stored on the server. The session has a default expiration time of 30 minutes.

The common operations for these objects include:

get, set, remove, containsKey

k.session.set("key", "value");
k.cookie.set("key", "value", 2); 
k.cache.set("key", "value", 12000);

var value = k.session.get("key"); 
var hasValue = k.cache.containsKey("key");
k.cache.remove("key");

Cache supports lazy generation of value

k.cache.getOrCreate("mykey", function () { return "myvalue" }, 12000);
