calling return RedirectToAction("Activity") outside controller

Question

I am building a fluent interface and would like to call the code below outside my controller...

return RedirectToAction("Activity");

How would I design this method? I have:

    public FluentCommand RedirectOnSuccess(string url)
    {
        if (IsSuccess)
            ;// make call here...

        return this;
    }

Note: IsSuccess is set here:

public FluentCommand Execute()
        {
            try
            {
                _command.Execute();
                IsSuccess = true;
            }
            catch (RulesException ex)
            {
                ex.CopyTo(_ms);
                IsSuccess = false;
            }
            return this;
        }

I call my fluent interface:

var fluent = new FluentCommand(new UpdateCommand(param,controller,modelstate)
.Execute()
.RedirectOnSucess("Actionname");

You could store an instance of the HttpContextBase as a field inside your fluent interface and when you need to redirect:

var rc = new RequestContext(context, new RouteData());
var urlHelper = new UrlHelper(rc);
context.Response.Redirect(urlHelper.Action(actionName), false);
