How to redirect nonWWW requests to WWW. requests

Typically when user goes to http://janaganamana.net/CountryXJgm.aspx instead of
http://www.janaganamana.net/CountryXJgm.aspx
the google map is not visible.-- reason - we registered GMap account to parent www.janaganamana.net...


In view of that we wanted to redirect all such requests of http://janaganamana.net/somepage* to
http://www.janaganamana.net/somepage*

This is how you do ....

<system.webServer>
<!--defaultDocument ................/-->
<rewrite>
<rules>
<rule name="SomeNameForThisRule" enabled="true" stopProcessing="true">
<match url=".*" />
<conditions>
<add input="{HTTP_HOST}" pattern="^[^\.]+\.[^\.]+$" />
<add input="{HTTPS}" pattern="off" />
</conditions>
<action type="Redirect" url="http://www.{HTTP_HOST}/{R:0}" />
</rule>
</rules>
</rewrite>
</system.webServer>
