Are ASP.NET MVC routes cached?

Question

I added a route to my asp.net mvc application to handle some json requests I need to do. This works great on my development pc, however when I installed in QA, the route isn't working at all. I tried to physically type in the address and get a "Bad Request". Can anyone assist with this? I have restarted IIS to try to clear any cache but still no luck. First time, I've seen this as I've made several changes to routes before.

routes.MapRoute(
            "FsrProblemTypesByEquipment",
            "Fsr/ProblemTypesByEquipment/{equipmentID}",
            new {controller = "Fsr", action = "ProblemTypesByEquipment", equipmentID = ""});

Do you still get a "bad request" if you take out the new route entry, but use the same test URL? If it is really a problem with your routing table, then your catchall route should get the request.

My guess is that the request is never getting to your routing table; IIS is catching the request before it gets passed to your application. If that is true, then it is a configuration problem in IIS, or IIS is unhappy with the construction of the URL for some reason.
