Question

I am currently working on a solution where we have a self-hosted ServiceStack layer running, but the problem is that I keep getting errors when I access it from the browser and the browser tries to get the favicon. As far as I can see there is no option of ignoring a specific route when running self-hosted?

I would have imagined something like

Routes.Ignore("favicon*")

a bit like the

Routes.Add<Foo>("/foo")

in my AppHost Configure method

Unlike MVC which uses a Http Module to process and hijack all requests, ServiceStack is built-on ASP.NET’s raw IHttpHandler interfaces. This means ServiceStack must handle any request matching the ServiceStack handler path (e.g. / or /api) by returning an IHttpHandler and isn’t able to Ignore them like they do in MVC.

You can however catch and handle all unhandled requests by registering a handler in IAppHost.CatchAllHandlers, e.g:

appHost.CatchAllHandlers.Add((httpMethod, pathInfo, filePath) => {
   if (pathInfo.StartsWith("favicon"))
      return new NotFoundHttpHandler();
});
