Adding a Default Route

When there are multiple routes in the IG configuration, they are ordered lexicographically, by route name. For example, 01-static.json is ordered before zz-default.json.

When IG processes a request, the request traverses the routes in the configuration. If the request matches the condition for 01-static.json it is processed by that route. Otherwise, it passes to the next route in the configuration. If a route has no condition, it can process any request.

A default route is the last route in a configuration to which a request is routed. If a request matches no other route in the configuration, it is processed by the default route.

Add a Default Route to the Configuration

Add the following route to IG:
```
$HOME/.openig/config/routes/zz-default.json
```
```
%appdata%\OpenIG\config\routes\zz-default.json
```
```
{
  "handler": "ReverseProxyHandler"
}
```
Notice the following features of the route:
- The route name starts with zz, so it is the last route that is loaded into the configuration.
- There is no condition property, so the route processes all requests.
- The route calls a ReverseProxyHandler with the default configuration, which proxies the request to the application and returns the response, without changing either the request or the response.

Check that the route system log includes a message that the file is loaded into the config:

INFO  o.f.o.handler.router.RouterHandler - Loaded the route with id 'zz-default' registered with the name 'zz-default'
