IE9 was released recently. It is brand new browser from Microsoft, which uses their new "Chakra" Javascript engine which makes it the fastest browser till date (even beating Chrome 10).
IE9 has an interesting feature called "Site Pinning". This blog post talks about how to change your website to make use of that and give the users of your website a "app" feel on Windows 7.
To begin with let us first add a shortcurt icon
Add this line in the HEAD section of your page.
| <link rel="shortcut icon" type=image/x-icon href="/images/shortcut.png" /> |
| |
and when you drag the tab in IE on to your Windows 7 taskbar, your shortcut icon shows up in task bar and the the you get a nice color scheme which is similar to your website when you open your website.

IE9 also lets you add "Jump list tasks", which can be done by the following snippet -
| <meta name="msapplication-task" content="name=Follow on Twitter;action-uri=http://twitter.com/subbaraokv;icon-uri=/images/twitter_ico.ico" /> |
| <meta name="msapplication-task" content="name=Subscribe to Feed;action-uri=http://www.bluegenegeek.com/blogs.rss.ashx;icon-uri=/images/feedicon.ico" /> |
| <meta name="msapplication-task" content="name=About Me;action-uri=http://www.bluegenegeek.com/About.aspx;icon-uri=/images/AboutMe.ico" /> |
The basic idea behind the above above snippet is you can add "tasks" with your own text and urls and have a nice little icon to go along with it.
Once this is done this is how it would look like -
Hope this helps
Cheers
