Global Cookie Checker

I was wondering if there is a specific location for me to check if a cookie that I am using on my nopCommerce4.4 exist on the whole site.  For example, I placed the cookie checker on the Home/Index controller; however, if a user tries to go to my site/contactUs page, they get right in without a cookie check.  Is it possible for me to check for the cookie before going to any of the controllers, like a global cookie checker?

You can implement it the following way:
1. Add a new filter to \Nop.Web.Framework\Mvc\Filters\WwwRequirementAttribute.cs
2. Implement appropriate logic in it
3. Add this attribute to the \Nop.Web\Controllers\BasePublicController.cs
