IIS URL Rewrite for redirect to FQDN

Question

I am trying to figure out the best URL rewrite rule to accomplish the following.

http://intranet/sites/default.aspx rewrite to http://intranet.domain.com/sites/default.aspx

http://intranet rewrite to http://intranet.domain.com

Also in IIS the URL binding is set to "intranet" for that web application

Hope that makes sense. Can someone please help with the rewrite rule?

This is the rule I would use:

<rule name="Intranet redirect" stopProcessing="true">
    <match url="(.*)" />
    <conditions>
        <add input="{HTTP_HOST}" pattern="^intranet$" />
        <add input="{HTTPS}" pattern="^OFF$" />
    </conditions>
    <action type="Redirect" url="http://intranet.domain.com/{R:0}" />
</rule>

It will match any requested path (url="(.*)") on the host exactly named http://intranet (pattern="^intranet$" and with https been turned off) and redirect it to http://intranet.domain.com/{R:0} (where {R:0} is a back reference containing whatever path was requested).
