how to redirect from one web site another web site in iis web server

Redirection is helpful in the following situations:

1. You change the location of your Web site and want to redirect users to your new site.

2. Your Web site is under construction and you want part of the site to be unavailable.

3. Your content is not located on the Web server.

4. You have changed the name of a virtual directory and you want users to be able to access files from the old URL.

In the simplest configuration, you need only set the enabled and destination attributes of the <httpredirect> element in order to redirect clients to a new location. However, additional elements like the exactDestination and httpResponseStatus attributes allow you to configure the end-user experience of the redirection by respectively specifying whether IIS 7 will return the destination URL exactly as entered and which HTTP response code to return to the Web client.
