title: simple and quick tool on linux to watch a http request coming
body: <p>A HTTP request is coming your way, hitting your machine on a port( assumed that you know the request url/route and the port)
  what is a simple and quick tool which helps you watch its headers, parameters being passed, using any language, or any tiny web server proxy, any tool.</p>
  
  <p>Being a ruby/rails guy, I quickly created a rails app, set its routes, ran it, and simply followed its logs.</p>
  
  <p>Curious to know how other web app developers deal with this.</p>
