Application state is one of the server side state management Mechanism which stores application memory on the server rather than persisting data in the Client side memory. Application state is a convenient repository for global data in a web application. Its use can severely limit the scalability of an application. Especially if it is used to store shared, updateable state. It is also an unreliable place to store data, because it is replicated with each application instance and is not saved if the application is recycled.
Application state is access through the Application Property of the HttpApplication Class, which returns an instance of class HttpApplicationState. This class is a named object Collection, which means that it can hold data of many type as part of a Key/Pair value.
Here we are discussing an example that how can you set Application key value pair.
