Hi Explain the difference between cache object and application object. Cache object Application object It stores the data on server side RAM as well as client side RAM. It always stores data on the server side RAM. Object maintains the static data as specified by the file dependency. Object maintains its data till the web application is shut down or Clear() method is called. It can be assigned data from web page and not from Global.asax file. Its data can be assigned using Global.asax file It is used for performance optimization. It is not used for performance optimization. The time for the cache can be defined using the Cache.Add() or Cache.Insert()overloaded method. It has not Timeouts or File Dependencies. The lifetime of cache is throughout the lifetime of an application or is based upon timeouts. Application variable/object stores an object with a scope of availability of the entire application unless explicitly destroyed. It supports different type of bindings like BasicHttpBinding WSHttpBinding WSDualHttpBinding etc. It can only use SOAP or XML for this. The classes that implement the Idictionary interface can be serialized. The classes which implement IEnumerable and ICollection interface can be serialized.

Application object is used to store the data related to application. This can be accessed by any user. Cache object are used to improve the performance of you application by using different caching mechanism. You can cache entire webpage control data object. You can create cache dependency based on key such as file database or input parameter.
