This tutorial shows you how to get your domain name(base url) from address bar in Google AppEngine, using self and urlparse
This is simple tutorial, more like a snippet. That shows you how you can get your domain from address bar. For example you are browsing our site and your URL in address bar is "/tutorial/get-self-base-url-appengine-urlparse". With this script you can get the domain out of it, that would be "www.browse-tutorials.com".
Base URL:
This is a part of my python file of my Google AppEngine application. I wanted to use base url in my view and this is how I do it. Don't forget to add the library.
