How to prevent a browser from calling an action method of MVC?

After using [ChildActionOnly] attribute, we restrict the action method to be called only from the View not directly by giving url in the browser address bar.

We can call the Child Action Only action method by calling @Html.Action("MyPartialResponse") method.

Here MyPartialResponse is the name of the action method whose attribute is set to [ChildActionOnly].

In general, Child Action Only method returns PartialView.
