you can use following rule by replacing the "domainname" with your domain name

<rule name="Redirect http://domainname.com to http://www.domainname.com HTTP" patternSyntax="ECMAScript" stopProcessing="true">
<match url=".*"></match>
<conditions>
<add input="{HTTP_HOST}" pattern="^domainname.com$"></add>
<add input="{HTTPS}" pattern="off"></add>
</conditions>
<action type="Redirect" url="http://www.domainname.com/{R:0}" redirectType="Temporary" appendQueryString="true"></action>
</rule>

Note: Make sure during the testing phase always use redirectType="Temporary" once you have verified that everything is working fine only then you should update it to redirectType="Permanent"
