title: CSS not updating on local python httpserver restart
body: <p>I'm fairly new to the world of web dev and http servers and the like, but I have a basic shell script as follows:</p>
  
  <pre><code>PORT=2600 
  if [[ $1 =~ ^[0-9]+$ ]]
    then PORT=$1
  fi
  
  echo "Starting local http server (ctrl-c to exit)"
  echo ""
  echo "  Demo:   http://127.0.0.1:$PORT/demo"
  echo ""
  python -m SimpleHTTPServer $PORT
  </code></pre>
  
  <p>It seems to work alright for just putting things up, but when I update the css file in my demo, it rarely and inconsistently will update the css displayed on the page. The changes to any html it renders fine, and it has occasionally shown the css changes, but I feel like I'm doing something fundamentally wrong here. Thoughts?</p>
