Answer / chandra prakash
the key difference between them is the added features
provided by the Cache object like the expiration policies
and dependencies. It means that the data stored in the cache
object can be expired/removed based on some predefined time
limit set by the application code or when the dependent
entity gets changed whereas this feature is not available in
the Application object.
Although when we want to save some database results like
dataset or datatable and we dont want to send the request
frequently to the database server, we use cache object.

Answer / prasanna
In application state we have to lock and unlock the
application.In cache it is not required. A cache object
supports dependencies such as file dependencies and SQL
dependencies.If there is any change in the file or in the
database tables cache expires.But an application does not
support dependencies.Cache objects employ expiration
policies whereas an application variable does not have the
expiration set.It has the life of the application.

Answer / sunaina
The main difference between the Cache and Application
objects is that the Cache object
provides cache-specific features, such as dependencies and
expiration policies.
