Do I need to do anything extra to get Glimpse to cough up details on a request that return the default 404 server error page on Cassini? By default 404 page, I mean the "Server Error in '/' Application" with a message of "The resource cannot be found" (as well as the HTTP 404 description, requested URL, and version info).
This project has some fairly complex routing, so I don't doubt I have something conflicting with what I am trying to do. I just want Glimpse to provide whatever details it can to point me in the right direction for fixing the problem.
I loaded up Glimpse via NuGet on an MVC3 project I am running through Visual Studio 2010's built-in hosting system (Cassini), and all works fine on previously working action methods and their resulting views. Since then, I added another action method that is proving difficult to hit via the default URL structure (e.g., /controller/action?someparam=x). Since I thought the Glimpse route data would be quite handy for determining what is going wrong here, I went looking for the eyeball in the corder of the default 404 page. Glimpse doesn't appear to be "attached" to this result.
UPDATE: Also doesn't work with RouteDebugger. Whatever I have wrong, it is high enough in the pipeline that nothing seems to be able to pin itself into the response.
UPDATE: The request URL wasn't working because I forgot I had this action set with [HttpPost]. That completely explains the 404, but not how to get any route information from the various utilities on the response sent back.
