Object Caching tutorials

  • ASP.NET allows you much more caching flexibility. You can use object caching to place any object in the cache. The object can be of any type: a data type, a web control, a class, a DataSet, and so on.

  • The object cache is stored in server memory, a limited resource, and the careful developer will conserve that resource. With that said, it is an easy way to buy significant performance benefits when used wisely, especially because ASP.NET will evict older items if memory becomes scarce.

  • The below table shows the list of properties of Object Catching

 

Properties

Description

Item

Specify the the default indexer for the ObjectCache class.

Name

Specify the name of a specific ObjectCache instance.

Host

Specify a reference to a managed hosting environment that is available to Object Cache implementations and that can provide host-specific services to ObjectCache implementations.

DefaultCacheCapabilities

When overridden in a derived class, gets a description of the features that a cache implementation provides.

 

Fragment Caching

  • Fragment caching does not actually cache a Web Form's code fragments directly; fragment caching refers to the caching of individual user controls (.ascx) within a Web Form.

  • Each user control can have independent cache durations and implementations of how the caching behavior is to be applied.

  • Fragment caching is useful when you need to cache only a subset of a page. Navigation bars, header, and footers are good candidates for fragment caching.

  • To cache a portion of a page, you must first encapsulate the portion of the page you want to cache into a user control. In the user control source file, add an OutputCache directive specifying the Duration and VaryByParam attributes. When that user control is loaded into a page at runtime, it is cached, and all subsequent pages that reference that same user control will retrieve it from the cache.

Example:

<!— UserControl.ascx —>

<%@ OutputCache Duration=”60” VaryByParam=”none'”%>
<%@ Control Language="'C#'" %>
