Use caching for your ASP.NET application.

One of the first things you should do before writing a line of application code is architect the application to exploit the ASP.NET Cache features to the maximum.

Rules to find candidates for caching:

• data that can be used more than once
• data that is general rather than specific to a given request or user
• data that is specific to a user or a request, but is long lived
• data that is expensive to create

Types of caching in an ASP.NET application:

• Data Caching - storing data in memory for quick access
• Page Output Caching - cache the output of a page so that the page does not need to be regernerated every time it is loaded
• Partial Page Output Caching - cache individual objects in your web application

Finally, do not cache too much to reduce the chance of an out-of-memory error. To prevent this monitor the memory usage of your ASP.NET application.
