    We have numerous subdomains going to specific pages:    ----->    ----->

    I tried using advanced url rewriter but it doesn't seem to match the domain name part:


    I am likely doing this wrong so... help?

    Someone please correct me if I'm wrong, but I don't think URL rewriting gets applied to the domain part of the URL.

    It would probably be better to accomplish your goal with IIS and not Sitefinity/ASP.NET.

    Just setup two new web sites in IIS and have IIS redirect them to the appropriate URL.

    Hi Gabe Sumner,

    Although the UrlRewriter works only in the same domain there is an option to achieve this functionality.
    Below, we are creating a CustomCmsHttpModule that inherits from CmsHttpModule and override GetUrl method.The idea is that we should get the original url string instead of the relative path.

    namespace Telerik.Cms.Web 
        public class CustomCmsHttpModule : CmsHttpModule 
            public CustomCmsHttpModule() 
            protected override string GetUrl(HttpContext context) 
                bool changed; 
                // get the  
                string rewritedUrl = AdvancedUrlRewriter.GetRewritedURL(context.Request.Url.OriginalString, out changed); 
                if (changed) 
                    // make redirect because the url is on atnother website. 
                    return rewritedUrl; 
                return string.Empty; 

    After you have succesfully created the module, you should register it in your web.config file - basically you need to replace the default one only in the sections below:

          <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> 
          <add name="Cms" type="Telerik.Cms.Web.CustomCmsHttpModule, App_Code"/> 


        <validation validateIntegratedModeConfiguration="false"/> 
          <remove name="ScriptModule"/> 
          <remove name="Cms"/> 
          <!--<remove name="LibraryModule"/>--> 
          <remove name="RadUploadModule"/> 
          <add name="ScriptModule" preCondition="managedHandler" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> 
          <add name="Cms" type="Telerik.Cms.Web.CustomCmsHttpModule, App_Code"/> 

    depending on the application pool mode you are using. Finally create your rule in urlrewrites node.

    Best wishes,

    Hi I believe we need the same functionality as what is being discussed in this thread. I've played with the code a bit and I cannot get it to work as (I think) is intended. When I match my url it is actually redirecting to the <rewrite> rule, which is great, but the browser is showing the <rewrite> url portion in the browser as well, which isn't so great.

    So for example (I'm simplifying below, so this isn't the exact rule I'm using):


    The browser makes the match on the <url> and redirects to <rewrite> url, but doesn't rewrite, so the user's browser will show: http://domain/subdomain/default.aspx.

    Am I missing a step, or was the code only intended as an example of how you override the GetUrl method?

    Any response would be greatly appreciated. A quick response would be even more appreciated as we may need to quickly rework our projects if we can't figure out a way to accommodate this functionality.

    As a side, we will not "own or control" the iis sub-domains and they will exist on a separate server. We can only get a redirect to our SF project folder.

    Hi David,

    Thank you for using our services.

    The UrlRewriter of Sitefinity works only with relative paths. It captures requests made to the application and does not involve matching the Urls to domains. If you wish to have subdomains such as: or
    which is covered by your license agreement you can use the approach in this KB article to setup subomain pages: Domain-Page mapping.

    Sincerely yours,
