有人能验证这段代码的完整性吗?我想用它装饰控制器,这样它就可以将url规范化为https和/或www。这是我对代码的第二次重写,因为第一次重写将自己抛出到无限重定向中,但不知怎么的,我仍然认为它不太存在。。。

public class NormalizeUrl : ActionFilterAttribute {
    private bool ForceHttps = false;
    private bool ForceWww = false;

    public NormalizeUrl() {
    }

    public NormalizeUrl(
        bool ForceHttps,
        bool ForceWww) {
        this.ForceHttps = ForceHttps;
        this.ForceWww = ForceWww;
    }

    public override void OnActionExecuting(
        ActionExecutingContext Context) {
        HttpRequestBase Request = Context.HttpContext.Request;
        HttpResponseBase Response = Context.HttpContext.Response;

        if (!Request.IsLocal) {
            Uri Uri;

            if (!Request.IsSecureConnection && ForceHttps) {
                if (ForceWww) {
                    Uri = new Uri(Uri.UriSchemeHttps + "://www." + Request.Url.Host.Replace("www.", string.Empty) + "/" + Request.Url.AbsolutePath);
                } else {
                    Uri = new Uri(Uri.UriSchemeHttps + "://" + Request.Url.Host.Replace("www.", string.Empty) + "/" + Request.Url.AbsolutePath);
                };
            } else if (!ForceHttps) {
                if (ForceWww) {
                    Uri = new Uri(Uri.UriSchemeHttp + "://www." + Request.Url.Host.Replace("www.", string.Empty) + "/" + Request.Url.AbsolutePath);
                } else {
                    Uri = Request.Url;
                };
            } else {
                Uri = Request.Url;
            };

            Response.RedirectPermanent(Uri.AbsoluteUri, true);
        };
    }
}
