ASP.NET Caching Interview Question:

Explain Page Output Caching?

Submitted by: Administrator

This type of caching is implemented by placing OutputCache directive at the top of the .aspx page at design time.
For example:
<%@OutputCache Duration= "30" VaryByParam= "DepartmentId"%>

The duration parameter specifies for how long the page would be in cache and the VaryByParam parameter is used to cache different version of the page.
The VaryByParam parameter is useful when we require caching a page based on certain criteria.
