title: HTTP requests trace
body: <p>Are there any tools to trace the exact HTTP requests sent by a program?</p>
  
  <p>I have an application which works as a client to a website and facilitates certain tasks (particularly it's a bot which makes automatic offers in a social lending webstite, based on some predefined criteria), and I'm interested in monitoring the actual HTTP requests which it makes.</p>
  
  <p>Any tutorials on the topic?</p>
