No ideas anybody ?

I can't be the only one having this problem. I have seen this on two different setups.

Message: System.Exception: Unhandled Error: ---> System.Web.HttpException: Not Found at DotNetNuke.HttpModules.UrlRewriteModule.OnBeginRequest(Object s, EventArgs e) in C:\DNN4.0.2_Source\Library\HttpModules\UrlRewrite\UrlRewriteModule.vb:line 63 at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) --- End of inner exception stack trace ---

Line 62-64 is:

If strURL.IndexOf("..") <> -1 Or strDoubleDecodeURL.IndexOf("..") <> -1 Then

Throw New HttpException(404, "Not Found")

End If

So, the the URL had ".." in it.  That's a good error, and not the problem.  I do need to track down the URL these are coming from though.

Here's the real problem.  Line 78 is:

Dim rules As Config.RewriterRuleCollection = Config.RewriterConfiguration.GetConfig().Rules

I think I've seen another post on the DNN boards about the .Rules returning a null reference.
