Caching is storing data in memory for quick access. Typically information that is costly to obtain (in terms of performance) is stored in the cache. One of the more common items stored in a cache in a Web application environment is commonly displayed database values; by caching such information, rather than relying on repeated database calls, the demand on the Web server and database server's system resources are decreased and the Web application's scalability increased.

Session variables can also be used to cache information in classic ASP, although, as with the cookie approach each session variable is specific to a particular user, and to tie a session variable to a particular user the user's browser must accept cookies. The advantages of using session variable's over cookies is that you can store objects, such as an array, or Dictionary object. Since session variables are stored on the Web server's memory, storing large objects in a user's session on a site with many simultaneous users can lead to reduced memory on the Web server.
