How to substitute ReturnUrl for certain action in asp.net mvc

Question

I would like to have different ReturnUrl for certain action in my ASP.NET MVC controller. Controller have Authorize attribute and OnEndRequest handler do the work for adding ReturnUrl to not authorized requests like so:

 protected override void OnEndRequest(object sender, EventArgs args)
 {
    HttpApplication app = (HttpApplication)sender;
    var location = resp.RedirectLocation;
    ...
 }

Then location will be used as value for ReturnUrl parameter.

The question: Is it possible, in some elegant way like some attribute on action, substitute value in resp.RedirectLocation or do it in different way?

Thanks.

You can send your return url to your custom Authorize attribute

   public class AuthAttribute:ActionFilterAttribute
    {
     private string _returnUrl { get; set; }
     public AuthAttribute(string url)
        {
            _returnUrl = url;
        }
     }
