      public class JSONActionRedirectResult
      extends ServletActionRedirectResult
      implements Redirectable

  Specialized form of `ServletActionRedirectResult` which takes care of situation that browser has a JS/AJAX context, there are no validation errors and action is executed. In this case a http redirect is harmful as browsers don't pass them to JS handlers. So this result produces a JSON response containing redirect data.

  To be used along with `JSONValidationInterceptor`.

  Response JSON looks like this:

      {"location": "$redirect url$"}
