The HTTP redirection role is not installed in Server 2008 by default. However this can be installed very easily using the following steps:
1. Click Start -> Administrative Tools -> Server Manager
2. Select “Roles” from the left
4. Check the box next to “HTTP Redirection”
5. Click Next -> Install
Now the “HTTP Redirect” heading will be available in IIS under the server name and under each individual site. There is no need to restart IIS to apply this change.
For instructions on creating a redirect with the newly installed role please refer to the following article:
