301使用负载均衡器Azure C＃重定向

Question

I am trying to do 301 redirect with following code:

protected void Application_PreRequestHandlerExecute(object sender, EventArgs e)
{
    var url = HttpContext.Current.Request.Url.ToString().ToLower();
    var contentId = GetIdFromUrl(url);

    var forwardedHost = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_HOST"];
    var proxiedBrand = HttpContext.Current.Request.Headers["HOST"].ToLower();
    var isRedirectionTrue = IsRedirectionArticleInCollection(contentId);
    var isForwardedHostTrue = forwardedHost.Contains("old.com");
    var urlRedir = url.Replace("v3", "www").Replace("old.com", "new.com");

    Logger.Warn("urlredir: " + urlRedir + ", ContentId: " + contentId + ", Url:" + url + ", isRedirectionTrue: " + isRedirectionTrue + ", ForwardedHost:" + forwardedHost + ", Host: " + proxiedBrand + ", IsForwardedHostTrue: " + isForwardedHostTrue);
    if (contentId > 0 && isRedirectionTrue && isForwardedHostTrue)
    {
        var urlToRedirectTo = "https://dev.www.new.com/";// url.Replace("v3", "www").Replace("old.com", "new.com");
        HttpContext.Current.Response.Status = "301 Moved Permanently";
        HttpContext.Current.Response.StatusCode = 301;
        HttpContext.Current.Response.AddHeader("Location", urlToRedirectTo);
        HttpContext.Current.Response.Redirect(urlToRedirectTo, false);
        HttpContext.Current.Response.End();
    }
}

Problem is that redirect is not working. I never get redirected to new domain, whatever i do. If I use hardcoded example dev.www.new.com it goes to dev.www.old.com domain, same thing happens with full url.

Is my redirect correct?

If I use hardcoded example dev.www.new.com it goes to dev.www.old.com domain, same thing happens with full url.

With your code in if judge sentences, it could correctly to go to dev.www.new.com with full url. Check the logger and set another log in if judge sentence to ensure you have run into if sentences.

Certainly, you could also use url rewrite to redirect based on the logic expressed in the rewrite rules . For more details, you could refer to this link .

If you still have any problem, please show me detailed your current domain and the redirected domain you want.
