Requests
All route handlers get called with a reference to a w::Request object. The Request object is a simple structure representing an HTTP request.

From the perspective of a route handler, the most interesting parts of a request are the headers, the params, the URI, and the request body, if one is provided.
Params defined in the route with the : syntax will appear in the params member, as well as any GET and POST parameters passed from the client.
