How to disable automatic browser caching from asp.Net mvc application?

Because I am having a problem with caching as it caches all links. But sometimes it redirected to DEFAULT INDEX PAGE automatically which stored it caching and then all the time I click to that link it will redirect me to DEFAULT INDEX PAGE.

So some one know how to manually disable caching option from ASP.NET MVC 4?

You can use the OutputCacheAttribute to control server and/or browser caching for specific actions or all actions in a controller.

Disable for all actions in a controller

[OutputCacheAttribute(VaryByParam = "*", Duration = 0, NoStore = true)] // will be applied to all actions in MyController, unless those actions override with their own decoration
public class MyController : Controller
{
  // ... 
}

Disable for a specific action:

public class MyController : Controller
{
    [OutputCacheAttribute(VaryByParam = "*", Duration = 0, NoStore = true)] // will disable caching for Index only
    public ActionResult Index()
    {
       return View();
    }
} 

If you want to apply a default caching strategy to all actions in all controllers, you can add a global action filter by editing your global.asax.cs and looking for the RegisterGlobalFilters method. This method is added in the default MVC application project template.

public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
    filters.Add(new OutputCacheAttribute
                    {
                        VaryByParam = "*",
                        Duration = 0,
                        NoStore = true,
                    });
    // the rest of your global filters here
}

This will cause it to apply the OutputCacheAttribute specified above to every action, which will disable server and browser caching. You should still be able to override this no-cache by adding OutputCacheAttribute to specific actions and controllers.
