Web.Config - Redirect from non-www to www. but ignore sub-domains

Question

User-1883366772 posted

Hi all,

On most sites I use the below code to redirect the non-www version of the domain name to the www. version of it.

In the case of one site, they have many sub-domains so I need my code to be more specific and only redirect in the case of there being no www. on the domain and to leave any other sub-domains intact.

so,

mydomain.co.uk (redirects to) www.mydomain.co.uk

admin.mydomain.co.uk (no redirect)

Here's my current global redirect code:

 <rewrite>
     <rules>
        <clear />
        <rule name="WWW Rewrite" enabled="false">
          <match url="(.*)" />
          <conditions>
            <add input="{HTTP_HOST}" negate="true" pattern="^www\." />
          </conditions>
          <action type="Redirect" url="http://www.{HTTP_HOST}/{R:0}" appendQueryString="true" redirectType="Permanent" />
        </rule>
    </rules>
</rewrite>
