Question

I am trying to figure out why my HttpRuntime.Cache collection is always empty when controller action is invoked by $.ajax? In actions invoked normally everything works perfectly and I can get my data from Cache. Maybe actions invoked by AJAX have some different lifecycle and Cache collection is not ready yet? This is my example code:

action:

[HttpPost]
public PartialViewResult SomeAjaxAction()
{
   // when receive ajax request HttpRuntime.Cache is always empty, but it shouldn't be
   SomeType item = HttpRuntime.Cache.Get("cache_key") as SomeType;

   return PartialView("SomeAjaxActionView", item); 
}

invocation:

$.ajax({
        type: 'POST',
        url: '/controller/SomeAjaxAction/',
        success: function (response) {
            alert(response);
        }
    });

Is there any way to fix it e.g by custom action filter?

ANSWER

Ok, I found answer here: Access to session when making ajax call to Asp.net MVC action So I imporoved my code with base.HttpRuntime.Cache.Get("key") and it works as expected!
