Rajeesh Menoth · Answer

Hi APPLICATION OBJECT: 1)Application object always stores data on the server side RAM example: Application[hits]=1; (key-value pair). 2)Application object maintains its data till the web application is shut down or we release the data manually by assigning null or Clear() method is called. 3)Application object has no Timeouts or File Dependencies. 4)Its data can be assigned using Global.asax file 5)Application object is not used for performance optimization. USED in maintaining hit counters data from readonly files/tables which can then be displayed on varrious web pages. CACHE OBJECT : 1)Cache object can store the data on server side RAM as well as client side RAM example: -- Cache[data]=asp.net; 2)Cache object maintains the static data as specified by the Absolute Expiration/ Sliding Expiration or File Dependency. The Time Period for Cache can be defined using the Cache.Insert() overloaded method or Cache.Add() method. It can be from seconds to years. 3)Cache object can be assigned data from web page and not from Global.asax file. 4)Cache is used for performance optimization. We retreive the Cache data from the Cache without repeating the full cycle again which is not so in the case of the Application object.

Application provides a place to store an Object that is scoped Application wide. Once created this object will live for the duration of your application unless you destroy it. Cache also provides application wide storage but also provides for automatic expirations (to allow you to reclaim memory) and expiration callbacks.
