How can you cache different version of same page using ASP.NET cache object ?

Output cache functionality is achieved by using "OutputCache" attribute on ASP.NET page header. Below is the syntax
  1. VaryByParam :- Caches different version depending on input parameters send through HTTP POST/GET. 
  2. VaryByHeader:- Caches different version depending on the contents of the page header. 
  3. VaryByCustom:-Lets you customize the way the cache handles page variations by declaring the attribute and overriding the GetVaryByCustomString handler. 
  4. VaryByControl:-Caches different versions of a user control based on the value of properties of ASP objects in the control.
