Welcome to the Q&A Forum

yes of course you are right, but i'm looking for people who have experience with this delay and have any idea how long it usually takes to get the rich snippet displayed in the serp. And how Google determines which mark up's are displayed.

1 - the absolute path. It's less error-prone. For example, if the rest of the URL was sometimes partly upper case, and other times completely lower case.

The site you've pointed to uses ajax to load its content. When the page loads there's a javascript snippet which takes over and adds the # to the page (hence why you're not seeing it as a httpd header). If you click on any other link you'll see that the base URL stays the same with some extra parameters on the end. There are potential crawling issues with this and a number of fixes (some Google documentation here, although this isn't the fix that the site in question is using: http://code.google.com/intl/en-US/web/ajaxcrawling/). So, in short, there's nothing fishy going on - it's just good old ajax content loading Matt
