Use of Data Caching

As per MSDN: "One instance of this class is created per application domain, and it remains valid as long as the application domain remains active. Information about an instance of this class is available through the Cache property of the HttpContext object or the Cache property of the Page object."

As per my knowledge, HttpContext and Page Object life is valid for single http request. So what is the use of Cache Property (Data caching) when I cant use it for another request?

HttpContext and Page might only be valid on a request basis. The cache however is on application level. Just because you can access the Cache object using HttpContext and Page does not mean they have the same lifespan.

MSDN is correct: HttpContext.Cache lives for your entire application lifecycle, not just over a request.

You are correct that the HttpContext lives per request, but the Cache object lives over the entire application life. The framework makes sure to assign the correct Cache instance whenever creating an HttpContext for you.
