never seen this. though off the stack trace is appear to be an ASP.NET problem
maybe you were calling Response.Redirect, which caused the HttpContext to loose data, then in the view you accessed the RawUrl directly. a possible fix will be - get the current url into the propertybag within the controller PropertyBag["returnUrl"] = Request.RawUrl; ... , then the view will simply render that value ($returnUrl) it also is a good thing, as it leaves HTTP related logic out of the view (which should deal with string manipulations etc.) On Thu, Jan 15, 2009 at 6:15 AM, Harry Dhillon <ha...@ripple6.com> wrote: > This error was reported by a user of our application.
