What is Session State In Asp.Net

  1. ASP.NET session state enables you to store and retrieve values for a user as the user navigates ASP.NET pages in a Web application. HTTP is a stateless protocol. This means that a Web server treats each HTTP request for a page as an independent request.Session is defined as the period of time that a unique user interacts with a Web application. When a new user begins to interact with the application, a new session ID is generated and associated with all subsequent requests from that same client and stored in a cookie on the client machine.

Caching In Asp.Net

Caching is the ability to store page output and data in memory for the first time it is requested and later we can quickly retrieve them for multiple, repetitious client requests. It is like keeping a copy of something for later use, so we can reduce the load factor on Web servers and database servers by implementing caching on a Web application.
Writing Code In C#
Cache.Add("dataset", dataset, null, System.Web.Caching.Cache.NoAbsoluteExpiration, new TimeSpan(0, 0, 60), System.Web.Caching.CacheItemPriority.Default, null);

How To Use Cookies ASP.NET.

The browser is responsible for managing cookies on a user system. Cookies can be created, accessed, and modified directly by script running on the client and pass between the client and server during requests.
Writing code in C#
Response.Cookies["UserName"].Value = "Ashok";
Response.Cookies["UserName"].Expires = DateTime.Now.AddDays(1);
