RAD Editor Dialogs Failing with UrlRewritingNet (Telerik KB Article: "Web.config registration missing!" not helpful)

I just swapped out CuteEditor for RAD Editor on my company's production site and the RAD Editor dialogs are not working - kicking the general error:

"Web.config registration missing! The Telerik dialogs require a HttpHandler registration in the web.config file..."

I thoroughly read through the KB article provided by Telerik, but I am still unable to get this resolved.

I have narrowed it down to the UrlRewritingNet assembly being used as I can comment that portion of the configuration out to get the RAD Editor working fully as desired. However, the Telerik KB article says to modify the code that handles the requested URL. I do not have any code doing this as everything is handled through configuration and the DLL.

Do I need to modify the virtualUrl property's regex??

My production environment is on IIS6 - however, I am locally on IIS7, so I have <system.webServer> running integrated mode in my config. I understand this should not affect the production environment which is on IIS6..?

Here is my configuration (the urlrewritingnet configuration is in a separate configSource file which is displayed after the general web.config):

Here is the specific section for urlrewritingnet:

<urlrewritingnet rewriteOnlyVirtualUrls="true" contextItemsPrefix="QueryString" defaultPage="default.aspx" xmlns="http://www.urlrewriting.net/schemas/config/2006/07">
  <rewrites>
    <add name="Root" virtualUrl="^~/(.*).aspx" rewriteUrlParameter="ExcludeFromClientQueryString" destinationUrl="~/rootPage.aspx?pageName=$1" ignoreCase="true"/>
  </rewrites>
</urlrewritingnet>

Is there a way to exclude Telerik.Web.UI.DialogHandler.aspx in my rewrites?

I've already set DialogHandlerUrl="~/Telerik.Web.UI.DialogHandler.aspx" in my RadEditor as indicated by another post I've come across.

It seems that your rewriter is catching all requests for .aspx files and the editor dialogs use .aspx extension by default. You will need to follow the last recommendation of the KB article. I have copied it here for clarity:

open the web.config file and replace Telerik.Web.UI.DialogHandler.aspx with Telerik.Web.UI.DialogHandler.axd set the RadEditor's DialogHandlerUrl property to "~/Telerik.Web.UI.DialogHandler.axd"
