Caching has been part of ASP.NET since its inception. Pages, page fragments, and arbitrary data elements can all be cached to increase performance. This session will go beyond the basics to demonstrate caching in a real web application. We will show how to use post-cache substitution in a real application (to display more than the current time like most demos!). The presentation will show how to cache pages based on a custom attribute for the logged in user. Lastly, we will show one way to design a business tier to take advantage of data caching while remaining loosely coupled to the UI.
