Hi there!

I have just migrated some sites to IIS7 from IIS6, and am experiencing problems with one of the sites.

When a request comes in for the site (www.ourdomain.com/site1/) with a trailing slash everything is fine. But if the trailing slash is left out (www.ourdomain.com/site1), then the request fails.

Apparently it doesn't do a 301 redirect on the slashl-less URL, resulting in ASP.NET throwing an exception. This is not happening with the other sites at the same domain.

What can be the cause of this?

EDIT: The exception I get is this: System.Web.HttpException: Failed to Execute URL. at System.Web.Hosting. ISAPIWorkerRequestInProcForIIS6.BeginExecuteUrl(String url, String method, String childHeaders, Boolean sendHeaders, Boolean addUserIndo, IntPtr token, String name, String authType, Byte[] entity, AsyncCallback cb, Object state) at System.Web.HttpResponse.BeginExecuteUrlForEntireResponse(String pathOverride, NameValueCollection requestHeaders, AsyncCallback cb, Object state) at System.Web.DefaultHttpHandler.BeginProcessRequest(HttpContext context, AsyncCallback callback, Object state) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)
