What is Partial Caching in ASP.NET?

Partial page output caching allows us to cache the rendering of a specific action on the view to enable the site to run faster. This can be a great technique to avoid unnecessary database calls to reduce server load and decrease client latency.

Partial caching or Fragment caching allows to cache specific portions of the page rather then whole page. It is done by implementing the page in different parts by creating everything in form of user controls and caching each user control individually.
