(defn welcome
  "A ring handler to process all requests for the web server.
  If a request is for something other than `/` then an error message is returned"
  [request]
  (if (= "/" (:uri request))
    {:status  200
     :headers {}
     :body    "<h1>Hello, Clojure World</h1>
               <p>Welcome to your first Clojure app.</p>
               <p>I now reload changes automatically</p> "}
    {:status  404
     :headers {}
     :body    "<h1>This is not the page you are looking for</h1>
               <p>Sorry, the page you requested was not found!</p>"}))
