Question

How does the DiggBar work?

I\'m trying to make an ASP.NET MVC DiggBar clone just for learning purposes and does anyone have a suggestion on how to specify the url

Answer 1

First of all, please don't do something like that, I don't know anyone that likes those things.

Something can be kept at the top like that using the CSS:

position: fixed;

As for specifying the URL, I'm not sure exactly what you're asking. When you click on a link on digg now, the destination URL is something like this:

http://digg.com/d1oIyx

The "d1oIyx" would just be used as a primary key into a database where they're storing the URL to be loaded in the bottom iframe.
