Application Insights lets you monitor your live application for: Availability - We'll test your URLs every few minutes from around the world. Performance - Detect and diagnose perf issues and exceptions. * Usage - Find out what users are doing with your app, so that you can make it better for them.

Python's SimpleHTTPServer is my goto friend for serving HTTP requests locally while developing stuff. Sometimes however you get caught with the browser caching things that you really don't want it to. CTRL+F5 usually works (it's a hardcoded pattern for me by now) but today I stumbled on a gotcha: cached JSON content that a page was pulling in.

The solution for me, was to modify SimpleHTTPServer to set HTTP headers to tell the browser not to cache. Here's the code:

#!/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)

Usage: python serveit.py 8080 to serve the local directory on port 8080.
