Kentico provides an easy to use redirection module that allows you to have all of your redirects in one place. However, the module does not allow you to redirect to external links. In this post I provide a quick tweak to the redirect module code that will allow you to enter the full path to redirect to external sites.
Open the RedirectionMethods.cs file found in App_Code > CMS_Modules > URLRedirection
Starting on line 16, replace the code block:
if (ValidationHelper.GetString(ds.Tables[0].Rows[0]["RedirectionType"], "301") == "301")
{
URLHelper.RedirectPermanent(URLHelper.ResolveUrl("~" + ValidationHelper.GetString(ds.Tables[0].Rows[0]["RedirectionTargetURL"], "/")), SiteInfoProvider.GetSiteName(site));
}
With the following:
if (ValidationHelper.GetString(ds.Tables[0].Rows[0]["RedirectionType"], "301") == "301")
{
string redirect_url = ValidationHelper.GetString(ds.Tables[0].Rows[0]["RedirectionTargetURL"], "/");
if(!(redirect_url.Contains("http://") || redirect_url.Contains("https://"))){
redirect_url = "~" + redirect_url;
}
URLHelper.RedirectPermanent(URLHelper.ResolveUrl(redirect_url), SiteInfoProvider.GetSiteName(site));
}
