How to use caching in ASP.NET Web API?

I am using ASP.NET MVC 4 with WEB API

I have the following action, in the action shown below, my service method makes a db call to

DoMagic()
method and returns an integer value which I am then using on every page, this action is called using an ajax call.

Below is my WEB API action :

[OutputCache(Duration = 86400, VaryByParam = "none")]
[ActionName("GetMyMagicNumber")]
public int GetMyMagicNumber()
{
if (WebSecurity.IsAuthenticated)
{
var revenue = _magicService.DoMagic();
return revenue;
}
return 0;
}


My question : I haved tried using
[OutputCache(Duration = 86400, VaryByParam = "none")]
and I excepted that only the first time the db call will be made and next subsequent request to this action will return me the cached value, but this is not happening.

A db call is again made, the db call takes time how do I get this working ?

Answer

Unfortunately, caching is not built into ASP.NET Web API.
