title: Compojure - Making HTTP call when route is hit
body: <p>I am new to Closure and trying out Ring and Compojure. I want to make an HTTP request when a user hits a route (to a third party API) and then use that response data in my HTML template
  . I know this is likely a very easy thing to pull off - but being new to language and the syntax I am a bit lost.</p>
  
  <pre><code> (defroutes app
      (GET "/" request
        ; try to GET "https://third-party-api" and do something with the response
      )
   )
  </code></pre>
  
  <p>What is the best practice and format for this - It's possible I am missing some key concepts in routing / response expectations here. Thanks very much!</p>
