State Management in ASP.NET

These are some of the important tips for State Management in ASP.Net:
• Sensitive state that should not be viewed or modified by user should be stored on server.
• If this sensitive data is to be sent to client then it should be encrypted beforehand regardless of storage mechanism employed.
• If any data is passed in through Query string in URL then this data is visible to user, hence sensitive data that can be used to control the application should be encrypted when using this technique.
• Application object was an ideal choice if data that was to be stored did not vary at all for life of the application. But Application Objects are displayed in trace Output. Hence sensitive data cannot be stored in Application Object.
• When dealing with single ASP.Net Page, View state is better choice than Query string for managing state.
• For long term data storage, cookie, session or cache are more appropriate data containers.
• Session object is one of the less efficient ways of storing user data as it holds memory for some time even after user has stopped using application. This affects the scalability of a busy site.
• Cache Object is particularly suitable when you expect to return the same information in same format for many different requests. It is the technique to temporarily store page output or application data either on client or server which can be reused to satisfy subsequent requests avoiding overhead of recreating same information. Caching is an important technique for building high performance and scalable server applications.
