#!/usr/bin/env python
import SimpleHTTPServer

class MyHTTPRequestHandler(SimpleHTTPServer.SimpleHTTPRequestHandler):
    def end_headers(self):
        self.send_my_headers()
        SimpleHTTPServer.SimpleHTTPRequestHandler.end_headers(self)

    def send_my_headers(self):
        self.send_header("Cache-Control", "no-cache, no-store, must-revalidate")
        self.send_header("Pragma", "no-cache")
        self.send_header("Expires", "0")


if __name__ == '__main__':
    SimpleHTTPServer.test(HandlerClass=MyHTTPRequestHandler)

Hello, by chance do you know how to disable the cache from command line?
I'm using this script:

function hostit(){
  PORT=${1:-'8080'}
  echo "Will try to host your directory $pwd at http://localhost:$PORT"
  python -m SimpleHTTPServer $PORT
}
