My Web.config’s system.webServer section initially looked like this,
<system.webServer>
....
<!--If you wish to use IIS rewrite rules,
see the documentation here:https://our.umbraco.org/documentation/Reference/Routing/IISRewriteRules-->
<!--<rewrite>
<rules></rules>
</rewrite> -->
</system.webServer>And my Web.Release.config looked like this,
<?xml version="1.0" encoding="utf-8"?>
<!-- For more information on using web.config transformation visit https://go.microsoft.com/fwlink/?LinkId=125889 -->
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<!--
In the example below, the "SetAttributes" transform will change the value of
"connectionString" to use "ReleaseSQLServer" only when the "Match" locator
finds an attribute "name" that has a value of "MyDB".
<connectionStrings>
<add name="MyDB"
connectionString="Data Source=ReleaseSQLServer;Initial Catalog=MyReleaseDB;Integrated Security=True"
xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
</connectionStrings>
-->
<system.web>
<compilation xdt:Transform="RemoveAttributes(debug)" />
<!--
In the example below, the "Replace" transform will replace the entire
<customErrors> section of your web.config file.
Note that because there is only one customErrors section under the
<system.web> node, there is no need to use the "xdt:Locator" attribute.
<customErrors defaultRedirect="GenericError.htm"
mode="RemoteOnly" xdt:Transform="Replace">
<error statusCode="500" redirect="InternalError.htm"/>
</customErrors>
-->
</system.web>
</configuration>Now I have to add a rule which redirects all non-www requests to www route. I accomplished the same by modifying the Web.config to,
<system.webServer>

<action type="Redirect" redirectType="Permanent" url="https://www.{C:1}/{R:0}" />
</rule>

</rewrite>
</system.webServer>
</configuration>Noticed the xdt:Transform=“Insert” in the line,
<rule name="Redirect Non WWW" stopProcessing="true" xdt:Transform="Insert">Which will add the rule to the Web.config automatically during publishing.
