Pinging Google (Re-indexing your links at google)

While playing around with django, I came across a library component called "Sitemap Framework". Its documentation teaches something about "forcing Google to re-index sitemap." I started googling around and found the official documentation from Google on  how to submit sitemap to google. I think this technique is pretty useful so that the links of your website will always be updated.

Going back to django... This framework has a built in module/function called "ping_google" which submits the website's sitemap.xml to Google's search engine. I tried using such and so now I'm still waiting for the web stat logs to verify if google re-indexed my website.
