Use a service that implements the Idistributedcache interface to enable memory caching. (for example, using a memory cache)This step needs to be used before the addsessi
Unlike cookies, Session status has no size limit. If there are extreme requirements, you can use Session to save G data. In addition, the Session can save more complex objects. For example, you can save a DataSet in the Session.
