Output cache functionality is achieved by using “OutputCache” attribute on ASP.NET page header. The syntax is as follows:-
<%@ OutputCache Duration="20" Location="Server"
VaryByParam="state"
VaryByCustom="minorversion" VaryByHeader="Accept-Language"%>
* VaryByParam :- Caches different version depending on input parameters send through HTTP POST/GET.
* VaryByHeader:- Caches different version depending on the contents of the page header.
* VaryByCustom:-Lets you customize the way the cache handles page variations by declaring the attribute and overriding the GetVaryByCustomString handler.
* VaryByControl:-Caches different versions of a user control based on the value of properties of ASP objects in the control.
