There are three types of caching supported by .NET 3.0

Absolute Expiration Caching
Sliding Caching
Cache Dependency Expiration caching

Absolute Expiration Caching

This is a form of caching wherein the expiration time is specified in advance. After a specific period of time, the contents of the cache get deleted.

Sliding Caching

Here, a time span is specified up to which the program checks for access. If no individual has accessed the site till the time span has expired, then the contents of the cache get deleted. So here, the time-span of the cache depends upon the popularity of the site.

Cache Dependency Expiration

In cache dependency expiration, the timespan of the cache depends on when the particular item on which the data is dependent is changed.
