This quick demo is useful for explaining what OAuth looks like to the end user. It is fully explained in the beginner’s guide but I find it very useful in this interactive format.
To use it in your own blog or site, use the following HTML code:
<iframe src=”http://nouncer.com/oauth/flow-demo.htm” height=”390px” width=”495px” scrolling=”no” frameborder=”no”/>


please rpovide the source for javascript and C# developers .
Sources are available at http://oauth.net
Thanks,
This simple example helped me to understand what you meant by a service provider and consumer
