+3. Set the `"Content-Type"` header in the response

 Exceptions thrown in router creation can be [handled with custom exception handler](../basics/error_messages.md). By default, exceptions thrown at runtime from a handler or a middleware are not caught by the `reitit.ring/ring-handler`. A good practice is to have a top-level exception handler to log and format errors for clients.

 The `:middleware` syntax in `reitit-ring` also supports Keywords. Keywords are looked up from the Middleware Registry, which is a map of `keyword => IntoMiddleware`. Middleware registry should be stored under key `:reitit.middleware/registry` in the router options. If a middleware keyword isn't found in the registry, router creation fails fast with a descriptive error message.

 ## When to use the registry?
 
 Middleware as Keywords helps to keep the routes (all but handlers) as literal data (i.e. data that evaluates to itself), enabling the routes to be persisted in external formats like EDN-files and databases. Duct is a good example, where the [middleware can be referenced from EDN-files](https://github.com/duct-framework/duct/wiki/Configuration). It should be easy to make Duct configuration a Middleware Registry in `reitit-ring`.
